Y DNA: Part 2 – The Dictionary of DNA

After my introductory article, Y DNA: Part 1 – Overview, I received several questions about terminology, so this second article will be a dictionary or maybe more like a wiki. Many terms about Y DNA apply to mitochondrial and autosomal as well.

Haplogroup – think of your Y or mitochondrial DNA haplogroup as your genetic clan. Haplogroups are assigned based on SNPs, specific nucleotide mutations that change very occasionally. We don’t know exactly how often, but the general schools of thought are that a new SNP mutation on the Y chromosome occurs someplace between every 80 and 145 years. Of course, those would only be averages. I’ve as many as two mutations in a father son pair, and no mutations for many generations.

Dictionary haplogroup.png

Y DNA haplogroups are quite reliably predicted by STR results at Family Tree DNA, meaning the results of a 12, 25, 37, 67 or 111 marker tests. Haplogroups are only confirmed or expanded from the estimate by SNP testing of the Y chromosome. Predictions are almost always accurate, but only apply to the upper level base haplogroups. I wrote about that in the article, Haplogroups and the Three Brothers.

Haplogroups are also estimated by some companies, specifically 23andMe and LivingDNA who provide autosomal testing. These companies estimate Y and mitochondrial haplogroups by targeting certain haplogroup defining locations in your DNA, both Y and mitochondrial. That doesn’t mean they are actually obtaining Y and mtDNA information from autosomal DNA, just that the chip they are using for DNA processing targets a few Y and mitochondrial locations to be read.

Again, the only way to confirm or expand that haplogroup is to test either your Y or mitochondrial DNA directly. I wrote about that in the article Haplogroup Comparisons Between Family Tree DNA and 23andMe and Why Different Haplogroup Results?.

Nucleotide – DNA is comprised of 4 base nucleotides, abbreviated as T (Thymine), A (Adenine), C (Cytosine) and G (Guanine.) Every DNA address holds one nucleotide.

In the DNA double helix, generally, A pairs with T and C pairs with G.

Dictionary helix structure.png

Looking at this double helix twist, green and purple “ladder rungs” represent the 4 nucleotides. Purple and green and have been assigned to one bonding pair, either A/T or C/G, and red and blue have been assigned to the other pair.

When mutations occur, most often A or T are replaced with their paired nucleotide, as are C and G. In this example, A would be replaced with T and vice versa. C with G and vice versa.

Sometimes that’s not the case and a mutation occurs that pairs A with C or G, for example.

For Y DNA SNPs, we care THAT the mutation occurred, and the identity of the replacing nucleotide so we know if two men match on that SNP. These mutations are what make DNA in general, and Y DNA in particular useful for genealogy.

The rest of this nucleotide information is not something you really need to know, unless of course you’re playing in the jeopardy championship. (Yes, seriously.) The testing lab worries about these things, as well as matching/not matching, so you don’t need to.

SNP – Single nucleotide polymorphism, pronounced “snip.” A mutation that occurs when the nucleotide typically found at a particular location (the ancestral value) is replaced with one of the other three nucleotides (the derived value.) SNPs that mutate are called variants.

In Y DNA, after discovery and confirmation that the SNP mutation is valid and carried by more than one man, the mutation is given a name something like R-M269 where R is the base haplogroup and M269 reflects the lab that discovered and named the SNP (M = Peter Underhill at Stanford) and an additional number, generally the next incremental number named by that lab (269).

Some SNPs were discovered simultaneously by different labs. When that happens, the same mutation in the identical location is given different names by different organizations, resulting in multiple names for the name mutation in the same DNA location. These are considered equivalent SNPs because they are identical.

In some cases, SNPs in different locations seem to define the same tree branching structure. These are functionally equivalent until enough tests are taken to determine a new branching structure, but they are not equivalent in the sense that the exact same DNA location was named by two different labs.

Some confusion exists about Y DNA SNP equivalence.

Equivalence Confusion How This Happens Are They the Same?
Same exact DNA location named by two labs Different SNP names for the same DNA location, named by two different labs at about the same time Exactly equivalent because SNPs are named for the the exact same DNA locations, define only one tree branch ever
Different DNA locations and SNP names, one current tree branch Different SNPs temporarily located on same branch of  the tree because branches or branching structure have not yet been defined When enough men test, different branches will likely be sorted out for the non-equivalent SNPs pointing to newly defined branch locations that divide the tree or branch

Let’s look at an example where 4 example SNPs have been named. Two at the same location, and two more for two additional locations. However, initially, we don’t know how this tree actually looks, meaning what is the base/trunk and what are branches, so we need more tests to identify the actual structure.

Dictionary SNPs before branching.png

The example structure of a haplogroup R branch, above, shows that there are three actual SNP locations that have been named. Location 1 has been given two different SNP names, but they are the same exact location. Duplicate names are not intentionally given, but result from multiple labs making simultaneous discoveries.

However, because we don’t have enough information yet, meaning not enough men have tested that carry at least some of the mutations (variants,), we can’t yet define trunks and branches. Until we do, all 4 SNPs will be grouped together. Examples 1 and 2 will always be equivalent because they are simply different names for the exact same DNA location. Eventually, a branching structure will emerge for Examples 1/2, Example 3 and Example 4..

Dictionary SNP branches.png

Eventually, the downstream branches will be defined and split off. It’s also possible that Example 4 would be the trunk with Examples 1 and 2 forming a branch and Example 3 forming a branch. Branching tree structure can’t be built without sufficient testers who take the NGS tests, specifically the Big Y-700 which doesn’t just confirm a subset of existing named SNPs, but confirms all named SNPs, unnamed variants and discovers new previously-undiscovered variants which define the branching tree structure.

SNP testing occurs in multiple ways, including:

  • NGS, next generation sequencing, tests such as the Big Y-700 which scans the gold standard region of the Y chromosome in order to find known SNPs at specific locations, mutations (variants) not yet named as SNPs, previously undiscovered variants and minimally 700 STR mutations.
  • WGS, whole genome sequencing although there currently exist no bundled commercial tools to separate Y DNA information from the rest of the genome, nor any comparison methodology that allows whole genome information to be transferred to Family Tree DNA, the only commercial lab that does both testing and matching of NGS Y DNA tests and where most of the Y DNA tests reside. There can also be quality issues with whole genome sequencing if the genome is not scanned a similar number of times as the NGS Y tests. The criteria for what constitues a “positive call” for a mutation at a specific location varies as well, with little standardization within the industry.
  • Targeted SNP testing of a specific SNP location. Available at Family Tree DNA  and other labs for some SNP locations, this test would only be done if you are looking for something very specific and know what you are doing. In some cases, a tester will purchase one SNP to verify that they are in a particular lineage, but there is no benefit such as matching. Furthermore, matching on one SNP alone does not confirm a specific lineage. Not all SNPs are individually available for purchase. In fact, as more SNPs are discovered at an astronomical rate, most aren’t available to purchase separately.
  • SNP panels which test a series of SNPs within a certain haplogroup in order to determine if a tester belongs to a specific subclade. These tests only test known SNPs and aren’t tests of discovery, scanning the useable portion of the Y chromosome. In other words, you will discern whether you are or are not a member of the specific subclades being tested for, but you will not learn anything more such as matching to a different subclade, or new, undiscovered variants (mutations) or subclades.

Subclade – A branch of a specific upstream branch of the haplotree.

Dictionary R.png

For example, in haplogroup R, R1 and R2 are subclades of haplogroup R. The graphic above conveys the concept of a subclade. Haplogroups beneath R1 and R2, respectively, are also subclades of haplogroup R as well as subclades of all clades above them on the haplotree.

Older naming conventions used letter number conventions such as R1 and R2 which expanded to R1b1c and so forth, alternating letters and numbers.

Today, we see most haplogroups designated by the haplogroup letter and SNP name. Using that notation methodology, R would be R-M207, R1 would be R-M173 and R2 would be R-M479.

Dictionary R branches.png

ISOGG documents Y haplogroup naming conventions and their history, maintaining both an alphanumeric and SNP tree for backwards compatibility. The reason that the alphanumeric tree was obsoleted was because there was no way to split a haplogroup like R1b1c when a new branch appeared between R1b and R1b1 without renaming everything downstream of R1b, causing constant reshuffling and renaming of tree branches. Haplogroup names were becoming in excess of 20 characters long. Today, the terminal SNP is used as a person’s haplogroup designation. The SNP name never changes and the individual’s Y haplogroup only changes if:

  • Further testing is performed and the tester is discovered to have an additional mutation further downstream from their current terminal SNP
  • A SNP previously discovered using the Big Y NGS test has since been named because enough men were subsequently discovered to carry that mutation, and the newly named SNP is the tester’s terminal SNP

Terminal SNP – It’s really not fatal. Used in this context, “terminal” means end of line, meaning furthest down and closest to present in the haplotree.

Depending on what level of testing you’ve undergone, you may have different haplogroups, or SNPs, assigned as your official “end of line” haplogroup or “terminal SNP” at various times.

If you took any of the various STR panel tests (12, 25, 37, 67 or 111) at Family Tree DNA your SNP was predicted based on STR matches to other men. Let’s say that prediction is R-M198. At that time, R-M198 was your terminal SNP. If you took the Big Y-700 test, your terminal SNP would almost assuredly change to something much further downstream in the haplotree.

If you took an autosomal test, your haplogroup was predicted based on a panel of SNPs selected to be informative about Y or mitochondrial DNA haplogroups. As with predicted haplogroups from STR test panels, the only way to discover a more definitive haplogroup is with further testing.

If you took a Y DNA STR test, you can see by looking at your match list that other testers may have a variety of “terminal SNPs.”

Dictionary Y matches.png

In the above example, the tester was originally predicted as R-M198 but subsequently took a Big Y test. His haplogroup now is R-YP729, a subclade of R-M198 several branches downstream.

Looking at his Y DNA STR matches to view the haplogroups of his matches, we see that the Y DNA predicted or confirmed haplogroup is displayed in the Y-DNA Haplogroup column – and several other men are M198 as well.

Anyone who has taken any type of confirming SNP test, whether it’s an individual SNP test, a panel test or the Big Y has their confirmed haplogroup at that level of testing listed in the Terminal SNP column. What we don’t know and can’t tell is whether the men whose Terminal SNP is listed as R-M198 just tested that SNP or have undergone additional SNP testing downstream and tested negative for other downstream SNPs. We can tell if they have taken the Big Y test by looking at their tests taken, shown by the red arrows above.

If the haplogroup has been confirmed by any form of SNP testing, then the confirmed haplogroup is displayed under the column, “Terminal SNP.” Unfortunately, none of this testers’ matches at this STR marker level have taken the Big Y test. As expected, no one matches him on his Terminal SNP, meaning his SNP farthest down on the tree. To obtain that level of resolution, one would have to take the Big Y test and his matches have not.

Dictionary Y block tree.png

Looking at this tester’s Big Y Block Tree results, we can see that there are indeed 3 people that match him on his terminal SNP, but none of them match him on the STR tests which generally produce genealogical matches closer in time. This suggests that these haplogroup level matches are a result of an ancestor further back in time. Note that these men also have an average of 5 variants each that are currently unnamed. These may eventually be named and become baby branches.

SNP matches can be useful genealogically, depending on when they occurred, or can originate further back in time, perhaps before the advent of surnames.

Our tester’s paternal ancestors migrated from Germany to Hungary in the late 1700s or 1800s, settling in a region now in Croatia, but he’s brick-walled on his paternal line due to record loss during the various wars.

The block tree reveals that the tester’s Big Y SNP match is indeed from Germany, born in 1718, with other men carrying this same terminal SNP originating in both Hungary and Germany even though they aren’t shown as a STR marker match to our tester.

You can read more about the block tree in the article, Family Tree DNA’s New Big Y Block Tree.

Haplotype – your individual values for results of gene sequencing, such as SNPs or STR values tested in the 12, 25, 37, 67 and 111 marker panels at Family Tree DNA. The haplotype for the individual shown below would be 13 for location DYS393, 26 for location DYS390, 16 for location DYS19, and so forth.

Dictionary panel 1.png

The values in a haplotype tend to be inherited together, so they are “unique” to you and your family. In this case, the Y DNA STR values of 13, 26, 16 and 10 are generally inherited together (unless a new mutation occurs,) passed from father to son on the Y chromosome. Therefore, this person’s haplotype is 13, 26, 16 and 10 for these 4 markers.

If this haplotype is rare, it may be very unique to the family. If the haplotype is common, it may only be unique to a much larger haplogroup reaching back hundreds or thousands of years. The larger the haplotype, the more unique it tends to be.

STR – Short tandem repeat. I think of a short tandem repeat as a copy machine or a stutter error. On the Y chromosome, the value of 13 at the location DYS393 above indicates that a series of DNA nucleotides is repeated a total of 13 times.

Indel example 1

Starting with the above example, let’s see how STR values accrue mutations.

STR example

In the example above, the value of CT was repeated 4 times in this DNA sequence, for a total of 5, so 5 would be the marker value.

Indel example 3

DNA can have deletions where the DNA at one or more locations is deleted and no DNA is found at that location, like the missing A above.

DNA can also have insertions where a particular value is inserted one or more times.

Dictionary insertion example.png

For example, if we know to expect the above values at DNA locations 1-10, and an insertion occurs between location 3 and 4, we know that insertion occurred because the alignment of the pattern of values expected in locations 4-10 is off by 1, and an unexpected T is found between 3 and 4, which I’ve labeled 3.1.

Dictionary insertion example 1.png

STR, or copy mutations are different from insertions, deletions or SNP mutations, shown below, where one SNP value is actually changed to another nucleotide.

Indel example 2

Haplotree – the SNP trees of humanity. Just a few years ago, we thought that there were only a few branches on the Y and mitochondrial trees of humanity, but the Big Y test has been a game changer for Y DNA.

At the end of 2019, the tree originating in Africa with Y chromosome Adam whose descendants populated the earth is comprised of more than 217,277 variants divided into 24,838 individual Y haplotree branches

A tree this size is very difficult to visualize, but you can take a look at Family Tree DNA’s public Y DNA tree here, beginning with haplogroup A. Today, there 25,880 branches, increased by more than 1000 branches in less than 3 weeks since year end. This tree is growing at breakneck speed as more men take the Big Y-700 test and new SNPs are discovered.

On the Public Y Tree below, as you expand each haplogroup into subgroups, you’ll see the flags representing the locations of where the testers’ most distant paternal ancestor lived.

Dictionary public tree.png

I wrote about how to use the Y tree in the article Family Tree DNA’s PUBLIC Y DNA Haplotree.

The mitochondrial tree can be viewed here. I wrote about to use the mitochondrial tree in the article Family Tree DNA’s Mitochondrial Haplotree.

Let’s Play DNA on Jeopardy!

My cousin, Kelly, e-mailed me saying that recently Jeopardy! had a category called:

I JUST TOOK A DNA TEST

I think this means that DNA is most definitely now a mainstream topic. Jeopardy has been having championships, and Kelly says that the contestants did quite well with these questions.

Let’s play along and see how we do. Write your “questions” to the following answers down on a piece of paper, and I’ll provide the Jeopardy questions at the end.

$400 Answer is below:

DNA TESTS CAN TELL YOU IF YOU ARE THIS 7-LETTER HOLDER OF RECESSIVE GENES FOR A GENETIC DISEASE

$800 Answer is below:

…BECAUSE I LOVE SCIENCE, I HAD THIS, MY FULL SET OF CHROMOSOMES, SEQUENCED TO BETTER UNDERSTAND MY FAMILY’S HISTORY OF MENTAL ILLNESS

The $1,200 Answer is below:

FOR INFO ON GREAT-GREAT-GRANDMA, GENETIC DATA PASSED ON FROM YOUR MOTHER CAN UE USED IN THE mtDNA TEST, NAMED FOR THIS ORGANELLE

The $1,600 Answer is below:

YOU CAN LEARN YOUR ETHNICITY USING DNA IN YOUR AUTOSOMES, NON-SEX CHROMOSOMES; MOST PEOPLE HAVE THIS MANY SETS OF AUTOSOMES

The $2,000 Answer is below:

DNA IS COMPOSED OF NUCLEOTIDES, WHICH CONTAIN 4 NITROGENOUS BASES REPRESENTED BY THESE 4 LETTERS

Ok, compile your questions to the above answers and let’s see how you did, according to Jeopardy:

  • $400 question – What is “a carrier?”
  • $800 question – What is “a genome?”
  • $1200 question – What is “mitochondria.”
  • $1600 question – What is “22?”
  • $2000 question – What is “A, C, T and G?”

How did you do? I tended to overthink the answers. For example, for the $800 question, the mental illness/health aspect of the answer made me think they were seeking Exome, which is the medical portion of the genome. Judges?

For the $1200 question, I thought that since they said mtDNA, the question couldn’t possible be mitochondria. That would be too easy because they gave that away in the answer – but mitochondria was correct.

For the last question, I overthought the answer and gave the full nucleotide name, not the abbreviation, even though the answer clearly said letters.

This is why I’m not on Jeopardy😊

How much DNA Jeopardy money did you accumulate? Now if we could just spend that money for DNA tests, right?

Y DNA: Part 1 – Overview

This is Part 1 of a series about Y DNA and how to use it successfully for genealogy.

If you’re in need of a brief DNA testing overview, please read 4 Kinds of DNA for Genetic Genealogy.

Y DNA testing has so much to offer. In this overview article, I’m touching briefly on each of the major functions and features of Y DNA testing. Following articles in this series will focus on how to utilize each tool for genealogy and harvesting every snippet of information available.

If you have Y DNA results, you can sign on to your account at Family Tree DNA and follow along. Throughout these articles, we’ll step through every tab and function, how to use them, and what they mean to you.

What is Y DNA and Why Do I Care?

Y DNA is what makes males, well, male.

The 23rd pair of human chromosomes consists of an X and a Y chromosome.

Female children inherit an X from both parents.

Male children inherit an X chromosome from their mother, but a Y from their father.

Generally, the Y chromosome follows the male surname line, so Estes males pass their Estes Y chromosome to their sons.

When adoptions occur, of course the surname of record does not match the biological surname associated with the Y chromosome – which is exactly why male adoptees take Y DNA tests.

Inheritance Path

In the example below, you can see that the light blue Y chromosome is passed from father to son to son to son to the male child in the current generation.

Y overview inheritance path

Click to enlarge

The dark blue maternal great-grandfather in this example also passes his Y chromosome to his son, but it stops there since the next generation in this tree is a female.

The light blue son at the bottom inherits a Y chromosome from his father, from ancestors all the way up that light blue line – along with his surname. The daughter doesn’t receive a Y chromosome nor do any females.

If you’re a male, you can test your own Y DNA of course.

If you’re a female, like the daughter, above, you must find a male in the line you seek to test. In this case, the brother, father, grandfather, paternal uncles and so forth represent her father’s Y DNA.

If you want information from any of the Y chromosome lineages in this chart that you don’t personally carry, you must find a male descended directly patrilineally from that line to test. It’s generally fairly easy to identify those people, because they will also carry the relevant surname. There are several examples in the article, Concepts – Who to Test for Your Father’s DNA.

Every Y DNA line has its own unique story for genealogists to harvest – assuming we can find an appropriate candidate for testing or find someone who has already tested. We’ll talk about how to see if your line may have already tested in the Projects section later in this article.

Why Y DNA Works

Y DNA is inherited from the patrilineal line directly. Unlike autosomal DNA, there is no genetic contribution from any females.

This uniquely male inheritance path allows us to use Y DNA for matching to other males beginning with the first generation, the father, then reaching back many generations providing a way to view our ancestral heritage beyond the line-in-the-sand boundary of surnames.

In other words, because Y DNA is not mixed with any DNA from the mothers, it’s very nearly identical to our patrilineal ancestors’ Y DNA – meaning it matches that of the father, and grandfather, reaching back many generations.

Some people, especially new autosomal testers, believe that Y DNA is ONLY useful for deep ancestry and not for genealogy. That’s ENTIRELY mistaken. Y DNA is extremely important in confirming descent from known ancestors. In fact, without Y DNA, you can’t tell the difference with autosomal testing between a child born to a male and a child born to the female of a couple. I wrote about that hereNo one wants to spend years barking up the wrong tree.

Y DNA testing is also the single best way to push the Y DNA genealogy back further in time. It can and does identify the geographic source, overseas, of the DNA lineage, through matches to other testers as well as haplogroup matches. These are things autosomal DNA simply cannot accomplish.

In fact, Y DNA did exactly that for my own Speak(es) line, connecting us genetically to the Speak family from Downham, Lancashire, England which then facilitated discovering the actual baptism document of our immigrant ancestor. Finding our English geographic source had eluded researchers for decades. A year later, a group of 20+ descendants visited Downham and stood in that very church.

Speak Family at St Mary Whalley

There simply is no better success story.

Migration Path Identified

Not only can Y DNA confirm recent ancestors and find ones more distant, by tracing a series of mutations, we can track our ancestor over time beginning with Y Line Adam, born in Africa tens of thousands of years ago to that church in an ancestral country and then to where we are today.

Y overview migration path.png

Mutations Happen

If mutations never occurred, the Y DNA of all males would be identical and therefore not useful for us to use for genealogy or to peer back in time beyond the advent of surnames.

Mutations do occur, just not on any schedule. This means that it’s difficult to predict how long ago we shared a common ancestor with someone else based solely on Y DNA mutations – although some types of mutations are better predictors than others.

A mutation might occur between a male and his father, or there might be no mutations for hundreds or even, potentially, thousands of years – depending on the marker type.

For example, in the Estes DNA project, one group of men have no STR (short tandem repeat) mutations in 8 generations. Others have several in the same number of generations.

Part of the success of matching genealogically with Y DNA testing has to do with:

  • The type of markers tested
  • The number of markers tested – testing fewer marker locations results in matches that are much less specific and therefore less relevant.
  • The luck of whether anyone else from your line has tested

The best results are between men who have taken the Big Y-700 test which provides for the largest number of STR markers and all SNPs (single nucleotide polymorphisms) , both previously known and discovered individually during that person’s Big Y test result.

Let’s take a look at the two different kinds of Y DNA markers and their mutations.

Two Kinds of Mutations

Y DNA can be tested for two different kinds of mutations, STR (short tandem repeat) markers and SNPs (single nucleotide polymorphisms.)

All DNA is comprised of four different nucleotides, abbreviated by A, C, G and T.

  1. A=adenine
  2. C=cytosine
  3. G=guanine
  4. T=thymine

When mutations take place, they can take the form of three types of mutations:

  • A deletion occurs when a nucleotide, or multiple nucleotides, fail to copy during reproduction. Therefore, that location or locations are then blank, with no DNA at that location permanently.
  • A replacement occurs when a nucleotide is replaced or swapped out with a different nucleotide. For example, an A could be replaced with one of the other nucleotides, and so forth.
  • An insertion occurs when a nucleotide or a group of nucleotides is duplicated and inserted between existing nucleotides.

Let’s look at how this actually works.

Indel example 1

Here’s an example segment of DNA.

A deletion would occur if the leading A (or a series of nucleotides) were simply gone.

Indel example 3

A replacement would occur if the first A above were to change to T or G or C as in the example below:

Indel example 2

A replacement is a SNP mutation.

An insertion would be where DNA is inserted between existing nucleotide locations.

STR example

Note the extra red CTs that have been inserted. Specifically, 4 extra CTs, for a total of 5 sets of CT. This is the definition of a STR, a short tandem repeat mutation.

STR markers, known as short tandem repeats, accrue what are similar to copy machine errors. This occurs when a specific segment of Y DNA gets repeated several times in a row. In other words, the copy machine gets stuck.

STR Markers

We purchase STR Y DNA tests from Family Tree DNA grouped into panels that include a specific number of markers.

Y overview STR results

Example of 37 marker results – click to enlarge

These panels consist of the following number of marker locations:

  • 12 markers (now obsolete)
  • 25 markers (now obsolete)
  • 37 markers
  • 67 markers (replaced by 111)
  • 111 markers
  • 500 markers bundled as part of the now-obsolete Big Y-500
  • 700 markers bundled with the Big Y-700

The more markers purchased, the more data points to be compared, and the more relevant and convincing the results.

What Matches See

The STR matches and SNP matches look different on the tester’s results page.

Y overview matches

Click to enlarge

People whom you match on STR panels can see that you do match, if you’ve opted-in to matching, but they can’t see specific differences or mutations. They see the name you’ve entered for yourself, your earliest known ancestor and your match can send e-mail to you. Aside from that, they can’t see your results or mutations unless you’ve joined a public project.

Y overview project

Click to enlarge

Within projects, participant names cannot be listed publicly. In other words, your matches can’t tell that it’s you unless you tell them your kit number or they recognize your earliest known ancestor on the project page and you are the only person with that ancestor.

The Big Y-700 test tests all STR markers in addition to scanning the entire Y chromosome for all SNP (haplogroup defining) mutations. They have the STR matches page like everyone else, but they also have an additional Big Ypage.

People who have taken the Big Y test see a different view of matches on their Big Y matches tab. This is true for either the original Big Y, Big Y-500 which includes a minimum of 500 STR markers or the current Big Y-700 test which includes a minimum of 700 STR markers. (You can always upgrade to the Big Y-700 from earlier tests.)

Y overview Big Y.png

For SNP markers only, above, Big Y matches can see who they match and the SNPs they do and don’t match with that person in common.

For STR markers available only under the Big Y umbrella, meaning above 111 markers, results are displayed under the Y DNA Matches tab in the Big Y STR Differences column, below.

Y overview Big Y STRs

Click to enlarge

You can easily see that only one man on this match list has also taken the Big Y test, and he had 2 differences out of 440 markers. That’s in addition to 2 differences in the first 111 markers, for a total of 4 differences (mutations) in 551 markers.

Researching Without Testing

The great news is that even if you’ve just ordered your test and are waiting for results, you can research and join projects now.

For that matter, you can research using public projects without testing by going to the main Family Tree DNA webpage, scroll down and simply entering the surname of interest into the search box.

New dashboard surname search

You’ll be directed to surname projects where you can view ancestors and results of anonymized project members.

Give it a try to see what comes up for your surnames of interest.

Project Results

Projects at Family Tree DNA provide testers with access to volunteer administrators who help users with various types of information. Administrators also cluster users in projects that are meaningful to their research.

Most Y DNA testers immediately join their surname project.

Using the Estes surname project as an example, you can see that I’ve grouped the project members in ways I feel will be helpful to their genealogy.

Y overview Estes project.png

The Paternal Ancestor Names are particularly helpful to testers as well as people who are interested in testing in order to determine whether or not they are descended from a specific line.

It’s very useful to be able to discern if someone from your line has already tested – because it provides someone for you to match against, or not, as the case may be.

Y overview hap C project.png

The haplogroup C-P39 Y DNA project is shown above with the Paternal Ancestor Name as provided by testers that reflects Native American and First Nations ancestors.

Another important project feature is the project map function, allowing testers in a specific haplogroup (C-P39 below) to view the locations of the earliest known ancestors of other members of the same haplogroup – whether project members match each other or not. Your Native ancestors traveled with theirs and descended from a common ancestor. Cool, huh!

What’s the story associated with the pin distribution of the C-P39 project, above? I wish we knew, and we may someday as research progresses. Whatever it is, it’s probably important genealogically.

Another type of project to join is a geographical or interest group project.

The Acadian AmerIndian Project welcomes descendants who have tested the Y, autosomal and/or mitochondrial DNA of the various Acadian families which includes French and English settlers along with First Nations indigenous ancestors.

Y overview Acadian.png

The map below shows the distribution of Y DNA members of the Acadian Amerindian project diaspora before and after Le Grand Dérangement” that scattered their descendants to the winds.

Y overview Acadian map.png

The pins on the Acadian Amerindian project map above are color coded by haplogroup.

Projects such as this facilitate genealogists discovering the haplogroup and related information about their direct line ancestor without personally testing.

Y overview Doucet.png

For example, if Germain Doucet born about 1641, part of the mustard-colored group above, is my ancestor, by viewing and/or joining this project, I can obtain this information about my ancestor. Project members can see more than casual browsers, because some testers only choose to display results to other project members and some projects are private, with results only displayed to project members. Many surname projects accept descendants who don’t carry the surname itself.

I obviously can’t personally test for Germain Doucet’s Y DNA myself, but thankfully, others who do descend patrilineally from Germain Doucet have been generous enough to test and share by joining this project.

Furthermore, I can contact the tester through the project administrator(s) and gain a great cousin with potentially LOTS of information.

Just think how useful Y DNA would be to genealogists if everyone tested!

Finding Projects to Join

I encourage all testers to join appropriate haplogroup projects. Often, more than one haplogroup project exists for each Y DNA letter, such as C or R. Generally, there are many subgroups for each core haplogroup and you may want to join more than one depending on your results.

I encourage testers to browse the selections and join other interest projects. For example, there are projects such as the Anabaptist Project which focuses on an endogamous religious sect, French-Swiss which is regional, or the American Indian project for people researching Native ancestry, in addition to relevant surname and haplogroup project(s). There are more than 10,000 total (well-organized) projects to choose from.

Your project selections may be a huge benefit to someone else as well as to your own research. Y DNA testing and matching is your best bet for jumping the pond and finding connections overseas.

How to Join Projects

Sign on to your personal page at Family Tree DNA and click on myProjects at the top, then on “Join A Project.”

2019: The Year and Decade of Change

2019 ends both a year and a decade. In the genealogy and genetic genealogy world, the overwhelmingly appropriate word to define both is “change.”

Everything has changed.

Millions more records are online now than ever before, both through the Big 3, being FamilySearch, MyHeritage and Ancestry, but also through multitudes of other sites preserving our history. Everyplace from National Archives to individual blogs celebrating history and ancestors.

All you need to do is google to find more than ever before.

I don’t know about you, but I’ve made more progress in the past decade that in all of the previous ones combined.

Just Beginning?

If you’re just beginning with genetic genealogy, welcome! I wrote this article just for you to see what to expect when your DNA results are returned.

If you’ve been working with genetic genealogy results for some time, or would like a great review of the landscape, let’s take this opportunity to take a look at how far we’ve come in the past year and decade.

It’s been quite a ride!

What Has Changed?

EVERYTHING

Literally.

A decade ago, we had Y and mitochondrial DNA, but just the beginning of the autosomal revolution in the genetic genealogy space.

In 2010, Family Tree DNA had been in business for a decade and offered both Y and mitochondrial DNA testing.

Ancestry offered a similar Y and mtDNA product, but not entirely the same markers, nor full sequence mitochondrial. Ancestry subsequently discontinued that testing and destroyed the matching database. Ancestry bought the Sorenson database that included Y, mitochondrial and autosomal, then destroyed that data base too.

23andMe was founded in 2006 and began autosomal testing in 2007 for health and genealogy. Genealogists piled on that bandwagon.

Family Tree DNA added autosomal to their menu in 2010, but Ancestry didn’t offer an autosomal product until 2012 and MyHeritage not until 2016. Both Ancestry and MyHeritage have launched massive marketing and ad campaigns to help people figure out “who they are,” and who their ancestors were too.

Family Tree DNA

2019 FTDNA

Family Tree DNA had a banner year with the Big Y-700 product, adding over 211,000 Y DNA SNPs in 2019 alone to total more than 438,000 by year end, many of which became newly defined haplogroups. You can read more here. Additionally, Family Tree DNA introduced the Block Tree and public Y and public mitochondrial DNA trees.

Anyone who ignores Y DNA testing does so at their own peril. Information produced by Y DNA testing (and for that matter, mitochondrial too) cannot be obtained any other way. I wrote about utilizing mitochondrial DNA here and a series about how to utilize Y DNA begins in a few days.

Family Tree DNA remains the premier commercial testing company to offer high resolution and full sequence testing and matching, which of course is the key to finding genealogy solutions.

In the autosomal space, Family Tree DNA is the only testing company to provide Phased Family Matching which uses your matches on both sides of your tree, assuming you link 3rd cousins or closer, to assign other testers to specific parental sides of your tree.

Family Tree DNA accepts free uploads from other testing companies with the unlock for advanced features only $19. You can read about that here and here.

MyHeritage

MyHeritage, the DNA testing dark horse, has come from behind from their late entry into the field in 2016 with focused Europeans ads and the purchase of Promethease in 2019. Their database stands at 3.7 million, not as many as either Ancestry or 23andMe, but for many people, including me – MyHeritage is much more useful, especially for my European lines. Not only is MyHeritage a genealogy company, piloted by Gilad Japhet, a passionate genealogist, but they have introduced easy-to-use advanced tools for consumers during 2019 to take the functionality lead in autosomal DNA.

2019 MyHeritage.png

You can read more about MyHeritage and their 2019 accomplishments, here.

As far as I’m concerned, the MyHeritage bases-loaded 4-product “Home Run” makes MyHeritage the best solution for genetic genealogy via either testing or transfer:

  • Triangulation – shows testers where 3 or more people match each other. You can read more, here.
  • Tree Matching – SmartMatching for both DNA testers and those who have not DNA tested
  • Theories of Family Relativity – a wonderful new tool introduced in February. You can read more here.
  • AutoClusters – Integrated cluster technology helps you to visualize which groups of people match each other.

One of their best features, Theories of Family Relativity connects the dots between people you DNA match with disparate trees and other documents, such as census. This helps you and others break down long-standing brick walls. You can read more, here.

MyHeritage encourages uploads from other testing companies with basic functions such as matching for free. Advanced features cost either a one-time unlock fee of $29 or are included with a full subscription which you can try for free, here. You can read about what is free and what isn’t, here.

You can develop a testing and upload strategy along with finding instructions for how to upload here and here.

23andMe

Today, 23andMe is best known for health, having recovered after having had their wings clipped a few years back by the FDA. They were the first to offer Health results, leveraging the genealogy marketspace to attract testers, but have recently been eclipsed by both Family Tree DNA with their high end full Exome Tovana test and MyHeritage with their Health upgrade which provides more information than 23andMe along with free genetic counseling if appropriate. Both the Family Tree DNA and MyHeritage tests are medically supervised, so can deliver more results.

23andMe has never fully embraced genetic genealogy by adding the ability to upload and compare trees. In 2019, they introduced a beta function to attempt to create a genetic tree on your behalf based on how your matches match you and each other.

2019 23andMe.png

These trees aren’t accurate today, nor are they deep, but they are a beginning – especially considering that they are not based on existing trees. You can read more here.

The best 23andMe feature for genealogy, as far as I’m concerned, is their ethnicity along with the fact that they actually provide testers with the locations of their ethnicity segments which can help testers immensely, especially with minority ancestry matching. You can read about how to do this for yourself, here.

23andMe generally does not allow uploads, probably because they need people to test on their custom-designed medical chip. Very rarely, once that I know of in 2018, they do allow uploads – but in the past, uploaders do not receive all of the genealogy features and benefits of testing.

You can however, download your DNA file from 23andMe and upload elsewhere, with instructions here.

Ancestry

Ancestry is widely known for their ethnicity ads which are extremely effective in recruiting new testers. That’s the great news. The results are frustrating to seasoned genealogists who get to deal with the fallout of confused people trying to figure out why their results don’t match their expectations and family stories. That’s the not-so-great news.

However, with more than 15 million testers, many of whom DO have genealogy trees, a serious genealogist can’t *NOT* test at Ancestry. Testers do need to be aware that not all features are available to DNA testers who don’t also subscribe to Ancestry’s genealogy subscriptions. For example, you can’t see your matches’ trees beyond a 5 generation preview without a subscription. You can read more about what you do and don’t receive, here.

Ancestry is the only one of the major companies that doesn’t provide a chromosome browser, despite pleas for years to do so, but they do provide ThruLines that show you other testers who match your DNA and show a common ancestor with you in their trees.

2019 Ancestry.png

ThruLines will also link partial trees – showing you ancestral descendants from the perspective of the ancestor in question, shown above. You can read about ThruLines, here.

Of course, without a chromosome browser, this match is only as good as the associated trees, and there is no way to prove the genealogical connection. It’s possible to all be wrong together, or to be related to some people through a completely different ancestor. Third party tools like Genetic Affairs and cluster technology help resolve these types of issues. You can read more, here.

You can’t upload DNA files from other testing companies to Ancestry, probably due to their custom medical chip. You can download your file from Ancestry and upload to other locations, with instructions here.

Selling Customers’ DNA

Neither Family Tree DNA, MyHeritage nor Gedmatch sell, lease or otherwise share their customers’ DNA, and all three state (minimally) they will not in the future without prior authorization.

All companies utilize their customers’ DNA internally to enhance and improve their products. That’s perfectly normal.

Both Ancestry and 23andMe sell consumers DNA to both known and unknown partners if customers opt-in to additional research. That’s the purpose of all those questions.

If you do agree or opt-in, and for those who tested prior to when the opt-in began, consumers don’t know who their DNA has been sold to, where it is or for what purposes it’s being utilized. Although anonymized (pseudonymized) before sale, autosomal results can easily be identified to the originating tester (if someone were inclined to do so) as demonstrated by adoptees identifying parents and law enforcement identifying both long deceased remains and criminal perpetrators of violent crimes. You can read more about re-identification here, although keep in mind that the re-identification frequency (%) would be much higher now than it was in 2018.

People are widely split on this issue. Whatever you decide, to opt-in or not, just be sure to do your homework first.

Always read the terms and conditions fully and carefully of anything having to do with genetics.

Genealogy

The bottom line to genetic genealogy is the genealogy aspect. Genealogists want to confirm ancestors and discover more about those ancestors. Some information can only be discovered via DNA testing today, distant Native heritage, for example, breaking through brick walls.

This technology, as it has advanced and more people have tested, has been a godsend for genealogists. The same techniques have allowed other people to locate unknown parents, grandparents and close relatives.

Adoptees

Not only are genealogists identifying people long in the past that are their ancestors, but adoptees and those seeking unknown parents are making discoveries much closer to home. MyHeritage has twice provided thousands of free DNA tests via their DNAQuest program to adoptees seeking their biological family with some amazing results.

The difference between genealogy, which looks back in time several generations, and parent or grand-parent searches is that unknown-parent searches use matches to come forward in time to identify parents, not backwards in time to identify distant ancestors in common.

Adoptee matching is about identifying descendants in common. According to Erlich et al in an October 2018 paper, here, about 60% of people with European ancestry could be identified. With the database growth since that time, that percentage has risen, I’m sure.

You can read more about the adoption search technique and how it is used, here.

Adoptee searches have spawned their own subculture of sorts, with researchers and search angels that specialize in making these connections. Do be aware that while many reunions are joyful, not all discoveries are positively received and the revelations can be traumatic for all parties involved.

There’s ying and yang involved, of course, and the exact same techniques used for identifying biological parents are also used to identify cold-case deceased victims of crime as well as violent criminals, meaning rapists and murderers.

Crimes Solved

The use of genetic genealogy and adoptee search techniques for identifying skeletal remains of crime victims, as well as identifying criminals in order that they can be arrested and removed from the population has resulted in a huge chasm and division in the genetic genealogy community.

These same issues have become popular topics in the press, often authored by people who have no experience in this field, don’t understand how these techniques are applied or function and/or are more interested in a sensational story than in the truth. The word click-bait springs to mind although certainly doesn’t apply equally to all.

Some testers are adamantly pro-usage of their DNA in order to identify victims and apprehend violent criminals. Other testers, not so much and some, on the other end of the spectrum are vehemently opposed. This is a highly personal topic with extremely strong emotions on both sides.

The first such case was the Golden State Killer, which has been followed in the past 18 months or so by another 100+ solved cases.

Regardless of whether or not people want their own DNA to be utilized to identify these criminals and victims, providing closure for families, I suspect the one thing we can all agree on is that we are grateful that these violent criminals no longer live among us and are no longer preying on innocent victims.

I wrote about the Golden State Killer, here, as well as other articles here, here, here and here.

In the genealogy community, various vendors have adopted quite different strategies relating to these kinds of searches, as follows:

  • Ancestry, 23andMe and MyHeritage – have committed to fight all access attempts by law enforcement, including court ordered subpoenas.
  • MyHeritage, Family Tree DNA and GedMatch allow uploads, so forensic kits, meaning kits from deceased remains or rape kits could be uploaded to search for matches, the same as any other kit. Law Enforcement uploads violate the MyHeritage terms of service. Both Family Tree DNA and GEDmatch have special law enforcement procedures in place. All three companies have measures in place to attempt to detect unauthorized forensic uploads.
  • Family Tree DNA has provided a specific Law Enforcement protocol and guidelines for forensic uploads, here. All EU customers were opted out earlier in 2019, but all new or existing non-EU customers need to opt out if they do not want their DNA results available for matching to law enforcement kits.
  • GEDmatch was recently sold to Verogen, a DNA forensics company, with information, here. Currently GEDMatch customers are opted-out of matching for law enforcement kits, but can opt-in. Verogen, upon purchase of GEDmatch, required all users to read the terms and conditions and either accept the terms or delete their kits. Users can also delete their kits or turn off/on law enforcement matching at any time.

New Concerns

Concerns in late 2019 have focused on the potential misuse of genetic matching to potentially target subsets of individuals by despotic regimes such as has been done by China to the Uighurs.

You can read about potential risks here, here and here, along with a recent DoD memo here.

Some issues spelled out in the papers can be resolved by vendors agreeing to cryptographically sign their files when customers download. Of course, this would require that everyone, meaning all vendors, play nice in the sandbox. So far, that hasn’t happened although I would expect that the vendors accepting uploads would welcome cryptographic signatures. That pretty much leaves Ancestry and 23andMe. I hope they will step up to the plate for the good of the industry as a whole.

Relative to the concerns voiced in the papers and by the DoD, I do not wish to understate any risks. There ARE certainly risks of family members being identified via DNA testing, which is, after all, the initial purpose even though the current (and future) uses were not foreseen initially.

In most cases, the cow has already left that barn. Even if someone new chooses not to test, the critical threshold is now past to prevent identification of individuals, at least within the US and/or European diaspora communities.

I do have concerns:

  • Websites where the owners are not known in the genealogical community could be collecting uploads for clandestine purposes. “Free” sites are extremely attractive to novices who tend to forget that if you’re not paying for the product, you ARE the product. Please be very cognizant and leery. Actually, just say no unless you’re positive.
  • Fearmongering and click-bait articles in general will prevent and are already causing knee-jerk reactions, causing potential testers to reject DNA testing outright, without doing any research or reading terms and conditions.
  • That Ancestry and 23andMe, the two major vendors who don’t accept uploads will refuse to add crypto-signatures to protect their customers who download files.

Every person needs to carefully make their own decisions about DNA testing and participating in sharing through third party sites.

Health

Not surprisingly, the DNA testing market space has cooled a bit this past year. This slowdown is likely due to a number of factors such as negative press and the fact that perhaps the genealogical market is becoming somewhat saturated. Although, I suspect that when vendors announce major new tools, their DNA kit sales spike accordingly.

Look at it this way, do you know any serious genealogists who haven’t DNA tested? Most are in all of the major databases, meaning Ancestry, 23andMe, FamilyTreeDNA, MyHeritage and GedMatch.

All of the testing companies mentioned above (except GEDmatch who is not a testing company) now have a Health offering, designed to offer existing and new customers additional value for their DNA testing dollar.

23andMe separated their genealogy and health offering years ago. Ancestry and MyHeritage now offer a Health upgrade. For existing customers, FamilyTreeDNA offers the Cadillac of health tests through Tovana.

I would guess it goes without saying here that if you really don’t want to know about potential health issues, don’t purchase these tests. The flip side is, of course, that most of the time, a genetic predisposition is nothing more and not a death sentence.

From my own perspective, I found the health tests to be informative, actionable and in some cases, they have been lifesaving for friends.

Whoever knew genealogy might save your life.

Innovative Third-Party Tools

Tools, and fads, come and go.

In the genetic genealogy space, over the years, tools have burst on the scene to disappear a few months later. However, the last few years have been won by third party tools developed by well-known and respected community members who have created tools to assist other genealogists.

As we close this decade, these are my picks of the tools that I use almost daily, have proven to be the most useful genealogically and that I feel I just “couldn’t live without.”

And yes, before you ask, some of these have a bit of a learning curve, but if you are serious about genealogy, these are all well worthwhile:

  • GedMatch – offers a wife variety of tools including triangulation, half versus fully identical segments and the ability to see who your matches also match. One of the tools I utilize regularly is segment search to see who else matches me on a specific segment, attached to an ancestor I’m researching. GedMatch, started by genealogists, has lasted more than a decade prior to the sale in December 2019.
  • Genetic Affairs – a barn-burning newcomer developed by Evert-Jan Blom in 2018 wins this years’ “Best” award from me, titled appropriately, the “SNiPPY.”.

Genetic Affairs 2019 SNiPPY Award.png

Genetic Affairs offers clustering, tree building between your matches even when YOU don’t have a tree. You can read more here.

2019 genetic affairs.png

Just today, Genetic Affairs released a new cluster interface with DNAPainter, example shown above.

  • DNAPainter – THE chromosome painter created by Jonny Perl just gets better and better, having added pedigree tree construction this year and other abilities. I wrote a composite instructional article, here.
  • DNAGedcom.com and Genetic.Families, affiliated with DNAAdoption.org – Rob Warthen in collaboration with others provides tools like clustering combined with triangulation. My favorite feature is the gathering of all direct ancestors of my matches’ trees at the various vendors where I’ve DNA tested which allows me to search for common surnames and locations, providing invaluable hints not otherwise available.

Promising Newcomer

  • MitoYDNA – a non-profit newcomer by folks affiliated with DNAAdoption and DNAGedcom is designed to replace YSearch and MitoSearch, both felled by the GDPR ax in 2018. This website allows people to upload their Y and mitochondrial DNA results and compare the values to each other, not just for matching, which you can do at Family Tree DNA, but also to see the values that do and don’t match and how they differ. I’ll be taking MitoYDNA for a test drive after the first of the year and will share the results with you.

The Future

What does the future hold? I almost hesitate to guess.

  • Artificial Intelligence Pedigree Chart – I think that in the not-too-distant future we’ll see the ability to provide testers with a “one and done” pedigree chart. In other words, you will test and receive at least some portion of your genealogy all tidily presented, red ribbon untied and scroll rolled out in front of you like you’re the guest on one of those genealogy TV shows.

Except it’s not a show and is a result of DNA testing, segment triangulation, trees and other tools which narrow your ancestors to only a few select possibilities.

Notice I said, “the ability to.” Just because we have the ability doesn’t mean a vendor will implement this functionality. In fact, just think about the massive businesses built upon the fact that we, as genealogists, have to SEARCH incessantly for these elusive answers. Would it be in the best interest of these companies to just GIVE you those answers when you test?

If not, then these types of answers will rest with third parties. However, there’s a hitch. Vendors generally don’t welcome third parties offering advanced tools and therefore block those tools, even though they are being used BY the customer or with their explicit authorization to massage their own data.

On the other hand, as a genealogist, I would welcome this feature with open arms – because as far as I’m concerned, the identification of that ancestor is just the first step. I get to know them by fleshing out their bones by utilizing those research records.

In fact, I’m willing to pony up to the table and I promise, oh-so-faithfully, to maintain my subscription lifelong if one of those vendors will just test me. Please, please, oh pretty-please put me to the test!

I guess you know what my New Year’s Wish is for this and upcoming years now too😊

What About You?

What do you think the high points of 2019 have been?

How about the decade?

What do you think the future holds?

Do you care to make any predictions?

Are you planning to focus on any particular goal or genealogy problem in 2020?

Triangulation in Action at MyHeritage

Recently, I published the article, Hitting a Genealogy Home Run Using Your Double-Sided Two-Faced Chromosomes While Avoiding Imposters. The “Home Run” article explains why you want to use a chromosome browser, what you’re seeing and what it means to you.

This article, and the rest in the “Triangulation in Action” series introduces triangulation at FamilyTreeDNA, MyHeritage, 23andMe, GedMatch and DNAPainter, explaining how to use triangulation to confirm descent from a common ancestor. You may want to read the introductory article first.

This first section, “What is Triangulation” is a generic tutorial. If you don’t need the tutorial, skip to the “Triangulation at MyHeritage” section.

What is Triangulation?

Think of triangulation as a three-legged stool – a triangle. Triangulation requires three things:

  1. At least three (not closely related) people must match
  2. On the same reasonably sized segment of DNA and
  3. Descend from a common ancestor

Triangulation is the foundation of confirming descent from a common ancestor, and thereby assigning a specific segment to that ancestor. Without triangulation, you might just have a match to someone else by chance. You can confirm mathematical triangulation, numbers 1 and 2, above, without knowing the identity of the common ancestor.

Reasonably sized segments are generally considered to be 7cM or above on chromosomes 1-22 and 15cM or above for the X chromosome.

Boundaries

Triangulation means that all three, or more, people much match on a common segment. However, what you’re likely to see is that some people don’t match on the entire segment, meaning more or less than others as demonstrated in the following examples.

FTDNA Triangulation boundaries

You can see that I match 5 different cousins who I know descend from my father’s side on chromosome 15 above. “I” am the grey background against which everyone else is being compared.

I triangulate with these matches in different ways, forming multiple triangulation groups that I’ve discussed individually, below.

Triangulation Group 1

FTDNA triangulation 1

Group 1 – On the left group of matches, above, I triangulate with the blue, red and orange person on the amount of DNA that is common between all of them, shown in the black box. This is triangulation group 1.

Triangulation Group 2

FTDNA triangulation 2

Group 2 – However, if you look just at the blue and orange triangulated matches bracketed in green, I triangulate on slightly more. This group excludes the red person because their beginning point is not the same, or even close. This is triangulation group 2.

Triangulation Group 3 and 4

FTDNA triang 3

Group 3 – In the right group of matches, there are two large triangulation groups. Triangulation group 3 includes the common portions of blue, red, teal and orange matches.

Group 4 – Triangulation group 4 is the skinny group at right and includes the common portion of the blue, teal and dark blue matches.

Triangulation Groups 5 and 6

FTDNA triang 5

Group 5 – There are also two more triangulation groups. The larger green bracketed group includes only the blue and teal people because their end locations are to the right of the end locations of the red and orange matches. This is triangulation group 5.

Group 6 – The smaller green bracketed group includes only the blue and teal person because their start locations are before the dark blue person. This is triangulation group 6.

There’s actually one more triangulation group. Can you see it?

Triangulation Group 7

FTDNA triang 7

Group 7 – The tan group includes the red, teal and orange matches but only the areas where they all overlap. This excludes the top blue match because their start location is different. Triangulation group 7 only extends to the end of the red and orange matches, because those are the same locations, while the teal match extends further to the right. That extension is excluded, of course.

Slight Variations

Matches with only slight start and end differences are probably descended from the same ancestor, but we can’t say that for sure (at this point) so we only include actual mathematically matching segments in a triangulation group.

You can see that triangulation groups often overlap because group members share more or less DNA with each other. Normally we don’t bother to number the groups – we just look at the alignment. I numbered them for illustration purposes.

Shared or In-Common-With Matching

Triangulation is not the same thing as a 3-way shared “in-common-with” match. You may share DNA with those two people, but on entirely different segments from entirely different ancestors. If those other two people match each other, it can be on a segment where you don’t match either of them, and thanks to an ancestor that they share who isn’t in your line at all. Shared matches are a great hint, especially in addition to other information, but shared matches don’t necessarily mean triangulation although it’s a great place to start looking.

I have shared matches where I match one person on my maternal side, one on my paternal side, and they match each other through a completely different ancestor on an entirely different segment. However, we don’t triangulate because we don’t all match each other on the SAME segment of DNA. Yes, it can be confusing.

Just remember, each of your segments, and matches, has its own individual history.

Imputation Can Affect Matching

Over the years the chips on which our DNA is processed at the vendors have changed. Each new generation of chips tests a different number of markers, and sometimes different markers – with the overlaps between the entire suite of chips being less than optimal.

I can verify that most vendors use imputation to level the playing field, and even though two vendors have never verified that fact, I’m relatively certain that they all do. That’s the only way they could match to their own prior “only somewhat compatible” chip versions.

The net-net of this is that you may see some differences in matching segments at different vendors, even when you’re comparing the same people. Imputation generally “fills in the blanks,” but doesn’t create large swatches of non-existent DNA. I wrote about the concept of imputation here.

What I’d like for you to take away from this discussion is to be focused on the big picture – if and how people triangulate which is the function important to genealogy. Not if the start and end segments are exactly the same.

Triangulation Solutions

Each of the major vendors, except Ancestry who does not have a chromosome browser, offers some type of triangulation solution, so let’s look at what each vendor offers. If your Ancestry matches have uploaded to GedMatch, Family Tree DNA or MyHeritage, you can triangulate with them there. Otherwise, you can’t triangulate Ancestry results, so encourage your Ancestry matches to transfer.

I wrote more specifically about triangulation here and here.

Let’s start by looking at triangulation at MyHeritage.

Triangulation at MyHeritage

MyHeritage offers triangulation integrated into their chromosome browser.

Triangulation MyHeritage matches.png

At MyHeritage, select DNA Matches from the DNA dropdown menu, then click on the purple “Review DNA Match” of the person you want to compare. We re looking at my cousin, Cheryl F.

Triangulation MyHeritage review.png

When reviewing my DNA match with Cheryl, I can see the list of people that Cheryl and I both match, including my mother, first on the list. In addition to my mother’s relationship to me, I can also see an estimate of how closely my mother matches the other person – in this case, Cheryl. Cheryl is my mother’s first cousin (1C) and my first cousin, once removed (1C1R.)

For triangulation, the important image is the little purple icon at right, above.

Clicking on the purple triangulation icon shows the segments where Cheryl, my mother and I all three match and triangulate.

Finding my mother among Cheryl’s close matches tells me immediately which parent I share with Cheryl.

The areas on the chromosome browser below in the rounded squares are triangulated, meaning that I match Cheryl and the other person (who just happens to be my mother) on that same segment.

Triangulation MyHeritage browser.png

Showing triangulation with Cheryl and my mother provides a great example, because of course I triangulate with Cheryl and my mother on every segment where I match Cheryl – because I inherited all of those segments through my mother.

However, as far as triangulation goes, the fact that two of those people are closely related, me and my mother, makes it the same as only two people matching – Mom and Cheryl. Still, since Mom and Cheryl are first cousins, that match confirms my great-grandparents.

Cheryl carries pieces of my great-grandparent’s DNA that my mother doesn’t though, so matches in common with Cheryl may prove very genealogically useful.

At the top right of this chromosome browser page, I can “add or remove DNA matches” from my match list. I can look through my match list to find another close relative to see if they triangulate or I can download my match list to see who else matches me on that same segment. Instructions for the file download are at the end of this section.

Same Segment Matches

To illustrate that people will match you on the same segment, but don’t match each other because they descend from different sides of your family, I’ll add some cousins from my father’s side of the family.

I’m going to select cousins Charlene and David, and remove my mother.

Below, we show chromosome 3 again, but the triangulation bracket is gone. This tells us that this segment does NOT triangulate between me and ALL three people.

Please note that I may triangulate with some of the people. The absence of the bracket only means that I don’t triangulate with ALL of them.

I already know that while I match Cheryl, Charlene and David on this segment, only David and Charlene match each other because they are both from my father’s side, and Cheryl doesn’t match either of them because she is on my mother’s side.

Triangulation MyHeritage segments

To prove this, and to determine triangulation groups, I can compare the people two by two and continue adding people to see if they continue to triangulate.

Below, I’ve removed Cheryl, and I triangulate on chromosome 3 with both Charlene and David. The triangulation bracket appears.

Triangulation MyHeritage chromosome 3

Therefore, I know that Charlene and David descend through one of my parents, and Cheryl through the other – even if I didn’t know anything else at this point.

To reiterate, triangulation at MyHeritage means triangulation with everyone showing at the same time on the chromosome browser.

Other Resources to Identify Common Ancestors

For additional information, I can check the match information with each person to see if our trees, surnames or locations intersect.

SmartMatches and Theories of Family Relativity each provide clues and help to explain why we might triangulate.

SmartMatches tell you that you and another person share an ancestor in your and their tree, BUT, that common person may not be a direct ancestor of one or both of you. You also may or may not be DNA matches, and if so, your DNA match may or may not be through that ancestor.

Theories of Family Relativity (TOFR,) on the other hand, tell you that not only do you have a DNA match with this person, but that you have a common ancestor, and who that ancestor is. Sometimes the connection is made for you, even if one or both of you don’t show that ancestor in your tree simply because you have not extended your tree back far enough in time.

I wrote about how to use Theories of Family Relativity here.

Downloading Matches

You can request to download your matches list and also your shared DNA segments at MyHeritage by clicking on the three dots to the right at the top of your match list, then click on the option you wish. The resulting files will be e-mailed to you a few minutes later. If they don’t arrive, be sure to check your spam filter.

Triangulation MyHeritage export.png

Downloading your match list and/or shared DNA segments is NOT the same thing as downloading your raw data file to upload elsewhere. You’ll find those instructions in the Transfer section later in this article.

What About You?

Do you have a tree at MyHeritage?

Triangulation MyHeritage tree tab.png

If not, click on Family Tree to create or upload one including not only direct line ancestors, but their children and grandchildren which facilitates and encourages the formation of Theories of Family Relativity.

Connecting Your DNA to Your Tree

Assigning your kit and those of family members to the proper profile card in your tree is very important, especially for the formation of Theories of Family Relativity

To suggest a theory, MyHeritage searches through all the possible links in the MyHeritage database meaning SmartMatches between trees, Record matches, record to record matches, etc.

If a DNA kit is not associated with an individual that is connected to ancestors, this reduces the probability that MyHeritage will be able to find a theory.

For example, if I took a DNA test but only have myself in the tree, not connected to my father and mother, but my father appears in another user’s tree (and there are more ancestors in that tree) MyHeritage won’t be able to find the information to generate a theory.

If I add my father, then the system has a common ancestor to work with.

When the TOFR algorithm runs, it’s trying to find any possible route to connect the two individuals (you and your DNA Match). If you are associated with individuals in multiple sites or trees, MyHeritage will try all of them and generate multiple paths for you to evaluate.

Have you assigned the kits of family members you manage to the proper place in your tree?

Triangulation MyHeritage tree.png

You can do this easily under the Manage DNA Kits option, under the DNA tab. Click on the three little dots to the right of the kit.

Triangulation MyHeritage assign dots.png

Then click assign the kit.

Triangulation MyHeritage assign kit.png

You’ll be prompted

Triangulation MyHeritage kit name.png

If you start typing, you’ll be prompted with the names of people in your tree.

Other Resources to Identify Common Ancestors

MyHeritage includes other tools to help you identify common ancestors as well, including:

  • SmartMatches where MyHeritage matches individuals in trees
  • AutoClusters showing groups of people that match you and each other
  • Shared Matches indicating common DNA matches between you and another DNA match
  • Shared Ancestral Surnames show common surnames, even if a common ancestor does not show in a tree
  • Shared Ancestral Places indicating common locations in trees
  • Shared Ethnicities comparing ethnicity between matches, a feature typically only beneficial if looking for a minority (to you) ancestry match
  • Genealogical Records including matches from other databases such as Geni.com and FamilySearch
  • Trees

Transfers

Have you tested family members, especially everyone in the older generations? You can transfer their kits from Ancestry, 23andMe or FamilyTreeDNA if they’ve already tested there to MyHeritage.

The article, Are You DNA Testing the Right People? explains how to determine who to test. Make sure you aren’t missing anyone that you need.

Gift Yourself a Trip to MyHeritage LIVE 2020 in Tel Aviv, Israel

MyHeritage LIVE 2020.png

You’ll excuse my exuberance if I say this would be the BEST GIFT EVER!!!

And the great thing is that you can gift yourself if Santa doesn’t do it for you. Early bird registration is only $100. At previous conferences, lunches were included too, as were  breaks with snacks and a generous goodie bag.

I attended the first and second MyHeritage LIVE conferences, in Oslo and Amsterdam, and they were absolutely AMAZING! I mean everything – the event itself, the people and companionship, the MyHeritage staff, Gilad’s opening sessions, the speakers and sessions, the food, the venue – everything.

MyHeritage 2019 Gilad keynote

Gilad Japhet, Founder and CEO of MyHeritage opening the conference in Amsterdam.

Oh, and the party, how could I possibly forget to mention the party.

MyHeritage Live Geoff Rasmussen and Daniel Horowitz

I think we found 2 of the Beatles at the party!

One of my favorite aspects of conferences is that we get to meet people in person that we’ve only met online, AND, we get to reconnect with old friends, strengthening bonds.

MyHeritage Live 4 musketeers

The 4 musketeers having a wonderful adventure in Amsterdam!

I will also say that MyHeritage does conferences right too. Nothing second class about these. Based on the conference price, they are heavily subsidized by MyHeritage – so take advantage of this wonderful opportunity.

The Announcement

Here’s the e-mail I received from MyHeritage:

Following the success of MyHeritage LIVE 2018 and 2019, I am delighted to announce that our third annual MyHeritage LIVE conference will take place from 25–26 October 2020 at the Hilton Tel Aviv in Israel! As one of the most celebrated genealogy events of the year, MyHeritage LIVE brings together family history enthusiasts, top international experts, and MyHeritage staff for two days of fascinating lectures covering the latest topics in genealogy and DNA. Each year, hundreds of MyHeritage users from around the world attend.

The venue is situated right on the Tel Aviv coastline with breathtaking views of the Mediterranean Sea. This year’s conference presents you with a wonderful opportunity to connect with fellow genealogy enthusiasts and tour a unique and beautiful country steeped in ancient history.

In addition to a plenary session from MyHeritage Founder and CEO Gilad Japhet, there will be multiple lectures, panels, and workshops covering genealogy and DNA, as well as sessions from local speakers covering Israeli resources and Jewish genealogy.

The Venue

In case you haven’t noticed yet, this conference hotel is literally on the beach, on the waters of the Mediterranean Sea.

MyHeritage LIVE 2020 beach.png

This is the miserable view out back.

MyHeritage LIVE 2020 hotel.png

And look, there’s a beautiful walkway and bikeway along the beach, with a seaside park right next door.

MyHeritage LIVE 2020 ballroom you.png

And the hotel ballroom where I suspect the conference will be held. Just mentally photoshop yourself into these pictures!

Am I tempting you yet? Well, read on…

Who’s Speaking?

The all-star lineup of speakers on the website includes many names you know, I’m sure.

MyHeritage LIVE speakers

Yes, I’ll be there along with many world-class speakers. Sometimes additional speakers are added over time.

MyHeritage LIVE speakers 2

Click to enlarge

I’m really looking forward to hearing these speakers. In particular, I want to learn more about Jewish genealogy. I have one ancestor who is reflected in records as being a Jewish merchant. My husband’s lines are lost in the Poland/Hungary (now Croatia) region during the war. He has great-great-grandparents who were Jewish, also reflected in his ethnicity results.

My own mitochondrial haplogroup J was born in this part of the world, and I want to visit a place so very central to the birth of humanity as we migrated out of Africa. Israel is “home” to all of us and we are related to her people, both ancient and modern.

I want to walk on that soil and touch those sacred places.

One of my cousins has already registered. Let’s have a reunion!

Registration

You can read about the conference, here and here.

Take a look at the fun video from the Amsterdam conference this fall.

You can register here.

Let me know, will I see you in Tel Aviv???

Get the Most for Your $$$

Are You DNA Testing the Right People?

We often want to purchase DNA kits for relatives, especially during the holidays when there are so many sales. (There are links for free shipping on tests in addition to sale prices at the end of this article. If you already know who to test, pop on down to the Sales section, now.)

Everyone is on a budget, so who should we test to obtain results that are relevant to our genealogy?

We tell people to test as many family members as possible – but what does that really mean?

Testing everyone may not be financially viable, nor necessary for genealogy, so let’s take a look at how to decide where to spend YOUR testing dollars to derive the most benefit.

It’s All Relative😊

When your ancestors had children, those children inherited different pieces of your ancestors’ DNA.

Therefore, it’s in your best interest to test all of the direct descendants generationally closest to the ancestor that you can find.

It’s especially useful to test descendants of your own close ancestors – great-great-grandparents or closer – where there is a significant possibility that you will match your cousins.

All second cousins match, and roughly 90% (or more) of third cousins match.

Percent of cousins match.png

This nifty chart compiled by ISOGG shows the probability statistics produced by the major testing companies regarding cousin matching relationships.

My policy is to test 4th cousins or closer. The more, the merrier.

Identifying Cousins

  • First cousins share grandparents.
  • Second cousins share great-grandparents.
  • Third cousins share great-great-grandparents.

The easiest way for me to see who these cousins might be is to open my genealogy software on my computer, select my great-great-grandparent, and click on descendants. Pretty much all software has a similar function.

The resulting list shows all of the descendants of that ancestor that I’ve entered in my software. Most genealogists already have or could construct this information with relative ease. These are the cousins you need to be talking to anyway, because they will have photos and stories that you don’t. If you don’t know them, there’s never been a better time to reach out and introduce yourself.

Who to test descendants software

Click to enlarge

People You Already Know

Sometimes it’s easier to start with the family you already know and may see from time to time. Those are the people who will likely be the most beneficial to your genealogy.

Who to test 1C.png

Checking my tree at FamilyTreeDNA, Hiram Ferverda and Evaline MIller are my great-grandparents. All of their children are deceased, but I have a relationship with the children born to their son, Roscoe. Both Cheryl and her brother carry parts of Hiram and Eva’s DNA their son John Ferverda (my grandfather) didn’t inherit, and therefore that I can’t carry.

Therefore, it’s in my best interest to gift my cousin, Cheryl and her brother, both, with DNA kits. Turns out that I already have and my common matches with both Cheryl and her brother are invaluable because I know that people who match me plus either one of them descend from the Ferverda or Miller lines. This relationship and linking them on my tree, shown above, allows Family Tree DNA to perform phased Family Matching which is their form of triangulation.

It’s important to test both siblings, because some people will match me plus one but not the other sibling.

Who’s Relevant?

Trying to convey the concept of who to test and not to test, and why, is sometimes confusing.

Many family members may want to test, but you may only be willing to pay for those tests that can help your own genealogy. We need to know who can best benefit our genealogy in order to make informed decisions.

Let’s look at example scenarios – two focused on grandparents and two on parents.

In our example family, a now-deceased grandmother and grandfather have 3 children and multiple grandchildren. Let’s look at when we test which people, and why.

Example 1: Grandparents – 2 children deceased, 1 living

In our first example, Jane and Barbara, my mother, are deceased, but their sibling Harold is living. Jane has a living daughter and my mother had 3 children, 2 of which are living. Who should we test to discover the most about my maternal grandparents?

Please note that before making this type of a decision, it’s important to state the goal, because the answer will be different depending on your goal at hand. If I wanted to learn about my father’s family, for example, instead of my maternal grandparents, this would be an entirely different question, answer, and tree.

Descendant test

Click to enlarge

The people who are “married in” but irrelevant to the analysis are greyed out. In this case, all of the spouses of Jane, Barbara and Harold are irrelevant to the grandmother and grandfather shown. We are not seeking information about those spouses or their families.

The people I’ve designated with the red stars should be tested. This is the “oldest” generation available. Harold can be tested, so his son, my first cousin, does not need to test because the only part of the grandparent’s DNA that Harold’s son can inherit is a portion of what his father, Harold, carries and gave to him.

Unfortunately, Jane is deceased but her daughter, Liz, is available to test, so Liz’s son does not need to.

I need to test, as does my living brother and the children of my deceased brother in order to recover as much as possible of my mother’s DNA. They will all carry pieces of her DNA that I don’t.

The children of anyone who has a red star do NOT need to test for our stated genealogical purpose because they only carry a portion of thier parent’s DNA, and that parent is already testing.

Those children may want to test for their own genealogy given that they also have a parent who is not relevant to the grandfather and grandmother shown. In my case, I’m perfectly happy to facilitate those tests, but not willing to pay for the children’s tests if the relevant parent is living. I’m only willing to pay for tests that are relevant to my genealogical goals – in this case, my grandparents’ heritage.

In this scenario, I’m providing 5 tests.

Of course, you may have other family factors in play that influence your decision about how many tests to purchase for whom. Family dynamics might include things like hurt feelings and living people who are unwilling or unable to test. I’ve been known to purchase kits for non-biologically related family members so that people could learn how DNA works.

Example 2: Grandparents – 2 children living, one deceased

For our second example, let’s change this scenario slightly.

Descendant test 2

Click to enlarge

From the perspective of only my grandparents’ genealogy, if my mother is alive, there’s no reason to test her children.

Barbara and Harold can test. Since Jane is deceased, and she had only one child, Liz is the closest generationally and can test to represent Jane’s line. Liz’s son does not need to test since his mother, the closest relative generationally to the grandparents is available to test.

In this scenario, I’m providing 3 tests.

Example 3: My Immediate Family – both parents living

In this third example, I’m looking from strictly MY perspective viewing my maternal grandparents (as shown above) AND my immediate family meaning the genealogical lines of both of my parents. In other words, I’ve combined two goals. This makes sense, especially if I’m going to be seeing a group of people at a family gathering. We can have a swab party!

Descendants - parents alive

Click to enlarge

In the situation where my parents are both living, I’m going to test them in addition to Harold and Liz.

I’m testing myself because I want to work using my own DNA, but that’s not really necessary. My parents will both have twice as many matches to other people as I do – because I only inherited half of each parent’s DNA.

In this scenario, I’m providing 5 tests.

Example 4: My Immediate Family – one parent living, one deceased

Descendants - father deceased

Click to enlarge

In our last example, my mother is living but my father is deceased. In addition to Harold and Liz who reflect the DNA of my maternal grandparents, I will test myself, my mother my living brother and my deceased brother’s child.

Because my father is deceased, testing as many of my father’s descendants as possible, in addition to myself, is the only way for me to obtain some portion of his DNA. My siblings will have pieces of my parent’s DNA that I don’t.

I’m not showing my father’s tree in this view, but looking at his tree and who is available to test to provide information about his side of the family would be the next logical step. He may have siblings and cousins that are every bit as valuable as the people on my mother’s side.

Applying this methodology to your own family, who is available to test?

Multiple Databases

Now that you know WHO to test, the next step is to make sure your close family members test at each of the major providers where your DNA is as well.

I test everyone at Family Tree DNA because I have been testing family members there for 19 years and many of the original testers are deceased now. The only way new people can compare to those people is to be in the FamilyTreeDNA data base.

Then, with permission of course, I transfer all kits, for free, to MyHeritage. Matching is free, but if you don’t have a subscription, there’s an unlock fee of $29 to access advanced tools. I have a full subscription, so all tools are entirely free for the kits I transfer and manage in my account.

Transferring to Family Tree DNA and matching there is free too. There’s an unlock fee of $19 for advanced tools, but that’s a good deal because it’s substantially less than a new test.

Neither 23andMe nor Ancestry accept transfers, so you have to test at each of those companies.

The great news is that both Ancestry and 23andMe tests can be transferred to  MyHeritage and FamilyTreeDNA.

Before purchasing tests, check first by asking your relatives or testing there yourself to be sure they aren’t already in those databases. If they took a “spit in a vial” test, they are either at 23andMe or Ancestry. If they took a swab test, it’s MyHeritage or FamilyTreeDNA.

I wrote about creating a testing and transfer strategy in the article, DNA Testing and Transfers – What’s Your Strategy? That article includes a handy dandy chart about who accepts which versions of whose files.

Sales

Of course, everything is on sale since it’s the holidays.

Who are you planning to test?

Genetic Affairs Reconstructs Trees from Genetic Clusters – Even Without Your Tree or Common Ancestors

Since Genetic Affairs launched in 2018, they’ve added a LOT of new functionality. I initially wrote about their clustering functionality here.

Genetic Affairs AutoClustering, SuperClusters and brand-new AutoTree tree reconstruction are to-die-for features for traditional genealogists. For adoptees or people seeking unknown parentage, they are the best thing since sliced bread, automating tasks previously peformed manually over labor-filled hours, days and months.

Why Genetic Affairs?

Genetic Affairs works with matches from three vendors; Ancestry, FamilyTreeDNA’s Family Finder test and 23andMe.

MyHeritage has integrated a version of Genetic Affairs directly into their product offering on the MyHeritage website so every MyHeritage DNA customer receives clustering functionality, free, through MyHeritage, but not tree reconstruction.

GedMatch has also implemented an autocluster version for Tier 1 users, but GedMatch’s version only works at GedMatch, of course, and does not include the new tree reconstruction feature.

This article pertains to the functionality of the features available directly through Genetic Affairs, including:

  • Clustering your matches visually to identify ancestral lines of people that match you and each other
  • Reports by cluster including common surnames and locations
  • Analysis of trees within each cluster to identify common ancestors
  • Partially reconstructs trees with your known ancestors for each cluster
  • Partially reconstructs trees between your matches even if you don’t have a tree or don’t share the common ancestor

Genetic Affairs provides visualization for linked DNA matches along with critically important clues to help you figure out just how you are related to these people, and these clusters of interrelated people. The Genetic Affairs user manual can be found here.

Analysis

Each time you run Genetic Affairs is called an analysis. Each analysis scans your kit at the selected vendor(s) for all current matches. A few minutes later, you receive a zip file via e-mail with two or three files depending on your selections at Genetic Affairs and the tree availabilty of the vendor:

  • Autocluster file including the visual clusters plus additional information
  • Excel spreadsheet of cluster members and relevant information such as common ancestors and common locations
  • Tree file containing reconstructed trees (23andMe does not support trees, so no trees are available for 23andMe clusters)

Let’s look at each feature. Grab a cup of coffee and head for the computer.

Selecting Analysis Options

I encourage you to experiment. Selecting a wider range of cM (centimorgans) results in a larger file, but may also mean that the analysis times out.

For this report, I’m utilizing my matches at FamilyTreeDNA and selected a cM range of 50 minimum and 250 maximum. I wanted a minimum cluster size of 2 people, meaning 2 in addition to me. This resulted in 249 total matches that met that criteria and 20 people who met the cM criteria but did not have another person with whom to cluster.

I tried a second analysis using 20 cM – 300 cM resulting in a much larger file with 499 people in the cluster group. Currently, 499 is the maximum that will be processed.

Genetic Affairs profiles.png

On the Genetic Affairs Profiles page, I can view all of the profiles I manage. Users can schedule updates where Genetic Affairs automatically scans for matches and produces reports.

Genetic Affairs my profiles

Click to enlarge

By clicking on the Autoscan button, you can schedule automated recurring scans with e-mail notification.

Genetic Affairs autoscan

Click to enlarge

You can scan daily, weekly, monthly or never – whatever interval you select.

You can select both the minimum level of DNA match and the minimum cM. The lowest you can select is 9cM.

You can view any e-mails that have been sent to you by Genetic Affairs. The green envelope means that there’s something in your e-mail box. This answers the question about whether the report was completed and sent. If the report has been sent, but is not in your e-mail, check your spam filter.

Starting the Scan

Back on the Genetic Affairs profiles page, you can initiate an autocluster by clicking on the AutoCluster button where you’ll see the options based on which vendor you’ve selected.

Genetic Affairs autocluster.png

For example, at Ancestry, you can include only people in a particular group or only starred matches.

Genetic Affairs Ancestry autocluster

Click to enlarge

23andMe includes surname enrichment and triangulated groups options.

Genetic Affairs 23andme autocluster.png

FamilyTreeDNA and Ancestry both include the “AutoTree – identify common ancestors from trees” option. It’s very important that you click this box if you select the “Default AutoCluster” option – or you won’t get the reconstructed trees.

Genetic Affairs default autocluster.png

Of course, you can always run the analysis again.

Genetic Affairs autotree.png

If you click on the “AutoTree AutoCluster” function, the AutoTree box is already checked for you.

Genetic Affairs autotree autocluster.png

Rule Based AutoCluster

The “Rule based AutoCluster” is a dream-come-true for people seeking unknown parents or ancestors in a relatively recent timeframe.

Genetic Affairs Rule Based Autocluster.png

The “Rule based AutoCluster” provides you with options that allow you to do three things:

  • NOT – Exclude your matches with someone else. For example, your mother has tested. You can use the NOT rule to exclude anyone you might match through your mother’s side, providing you with clusters from your father’s side.
  • AND – Combine your results with someone else’s. If you have identified a half-sibling, you can view only clusters of only people who match you AND your half sibling.
  • OR – Combined rules. You can request a cluster of everyone in clusters with person A but not in a cluster with person B. In this case, if you match a number of half siblings, you can include all of their matches, except people who match them through their “other” parent, if that parent has tested.

Genetic Affairs has provided some graphics and examples here, but you may have to be a member of the site to access this page because the options are customized for you. So I’ll include the non-customized information, below. You can click these to open in a separate window and enlarge.

Read the details of how these tools work. They are powerful, so don’t assume you understand without reading carefully.

Now let’s cluster!

Clustering Your Matches

Genetic Affairs autocluster order.png

At Genetic Affairs, if you initiate clustering by clicking on the AutoCluster button, you’ll need to put a checkmark in the AutoTree function box. If you began by clicking the AutoTree button, the box is automatically checked for you.

A few minutes later, you’ll receive an email with a zipped file. Save this file to someplace on your computer where you can find it, and open the zipped file by clicking.

Genetic Affairs zip file.png

You’ll see the files, above.

Click on the chrome AutoCluster HTML file which will display in your browser.

The first thing you will see is your visual autocluster. It’s so much fun to watch your matches “fly” into place!

Each of the people in this cluster are somehow related to the other people in the custer who have cells of the same color. The people with grey cells are included in two clusters – meaning the one to the right and the one above, both.

Genetic Affairs cluster.png

The names of the matches are listed to the left and above the display.

The legend is to the right.

Genetic Affairs cluster legend.png

I have a total of 41 clusters.

Scrolling down the page, each cluster has additional information, and each column is searchable or selectable, including comments I’ve entered at the vendor.

Genetic Affairs autocluster info

Click to enlarge

Just by looking at these first 3 matches, I know immediately which side of the family and which ancestors are involved with this cluster. I can look at my notes, to the right, which indicate whether I’ve identified our common ancestor. I paint identified matches at DNAPainter which I’ve entered into the notes field at the vendor.

If I’m signed in to my account at the vendor, I can click on my match’s tree link, above, and take a look. Keep in mind that these people can be related to you, and each other, through multiple ancestors.

Genetic Affairs autocluster members.png

You can hover over any person in the grid, above, to view additional information. For each person whose square is grey, indicating membership in (at least) two clusters, you can hover over the grey square and view the members of both clusters. In this case, I’m hovered over the grey square of Brooke and E.H and the black box shows me who is in both people’s clusters.

Note that while a match could be related to you through several ancestors, and hence be in more than 2 clusters, because of the grid nature of clustering, a match can only be displayed in a maximum of 2 different clusters.

Looking at the auto-generated table below, I see the common surnames in cluster 1. Keep in mind that many of these people maybe related to each other through a spouse that you aren’t. Your ancestor’s brother’s children, for example, are also related to each other through your ancestor’s brother’s wife.

Genetic Affairs surnames.png

I know that Vannoy is the common line, but Upton isn’t my ancestor – at least not that I know of. However, a surname with 20 people in a cluster needs to be investigated and evaluated. Do I have any missing wives in this line? Here’s a really great place to start digging.

In this case, it turns out that one of my ancestor’s children married an Upton, and several of his descendants have tested.

Let’s see what other tools we have.

The Ancestor Spreadsheet

Opening the spreadsheet file, I see several rows and columns.

The common ancestor between the people in the rows is listed at left. The green cells are from my tree.

Two example ancestors are shown above, Mary McDowell and William Harrell, who just happen to have been married to each other.

These people share a common ancestor in their trees, an ancestor that isn’t in my tree. Presumably this is an ancestor I don’t share with them – or one I haven’t identified.

For example, “Bev” and “van” share William Grubb. “Vicki” and “Mark” share Martha Helen Smith. I don’t share either of these ancestors, but Martha Smith married Alvis Winster Bolton, the son of my ancestor – so I know why Martha Helen Smith appears as a common person in the trees of my matches, but not me.

Further down in the same cluster, I notice that one match shares multiple lines in our trees. Therefore, our DNA match could be on either line, or some segments from one line and some from the other.

Scrolling to the bottom of each cluster’s sheet, common locations are provided.

While the designation of “Tennessee” isn’t terribly exciting, scrolling further down provides a list by county, and that IS exciting, especially if you’re chasing a brick wall. Sometimes a group of ancestors in a location where you’re seeking a female’s family is very suggestive especially when combined with ancestral names and surnames.

Let’s move on to the third group of files, Trees.

The Tree File

Click on the tree file and you’ll see the following.

Reconstructed Trees

For each cluster where trees can be reconstructed, you’ll see two files for cluster 1:

  • Ancestors 1
  • Tree 1

Opening the file labeled Ancestors 1, I see the following information for the first ancestor, meaning a common ancestor between the two people listed below that ancestor. You can click to enlarge these images.

Opening the corresponding Tree 1 file, I see that Genetic Affairs has reconstructed the tree between me and the other testers as best it can based on the provided trees.

Looking at the tree for cluster 3, below, I see this line in cluster 1, above, has been extended because Sarah, the pink match and me all share a common ancestor, Elizabeth Shepherd.

Looking at another cluster, below, while I don’t share an ancestor in a tree, three people that I match at a relatively high level do.

As you can see, their common ancestor is Anne Adelaide Chiasson. This is my Acadian line, so our common ancestor or ancestors must be someplace on up that tree, or the result of an undocumented adoption, or a missing ancestor in our trees.

Constructing the trees of your matches to each other, even when you don’t have a common ancestor in your tree, is the best feature of all.

Clustering plus tree reconstruction, especially in combination with the other clues, is the key to breaking through those unyielding  brick walls.

Super AutoClusters

Just as I was getting ready to publish this article, Genetic Affairs released a new feature called Super AutoCluster.

I absolutely love this, because it combines your clusters from multiple vendors – today Ancestry, who does not provide segment information, along with Family Tree DNA, who  provides invaluable segment information.

This combination can be extremely powerful.

To begin a Super AutoCluster, click on that option under an AncestryDNA kit that also has a kit at Family Tree DNA. Both kits need to have a profile at Genetic Affairs.

Genetic Affairs supercluster.png

Next, you’ll see the screen confirming the kits to use. The combined autocluster tool is limited to a total of 500 matches, or 250 at each account. However, that’s more than enough to make some great progress.

Press “Perform Analysis.”

Drum roll please…

Voila, your combined cluster.

Genetic Affairs supercluster cluster

Click to enlarge

In this example, you can see the large peach and purple Ancestry clusters. The green red, brown and pink smaller clusters are Family Tree DNA clusters. The Family Tree DNA clusters have tiny little Fs in their cells. If you click the above graphic to enlarge, you can see the Fs.

However, the grey cells that intersect the two clusters, meaning an Ancestry and a Family Tree DNA cluster, are found in both of those clusters, connecting the clusters for you logically.

If you look closely at the cells labeled here with “common names,” you’ll see “N” in the cells indicating a common names for you to check out within that cluster.

The “Common Ancestors” box shows the people who connect to both clusters.

There are also a number of people that span the green and red Family Tree DNA clusters too.

Genetic Affairs then proceeds to combine the clustered DNA matches and trees for you from both vendors.

In addition to the cluster graph and spreadsheet information that now includes combined information, you’ll see a much larger clustered tree.

And again, the best part is that even if you don’t know how you connect to people through trees, their tree and ancestors will be connected, even if you’re absent. You’ll be present in the genetic cluster itself, so you can work the combined tree cluster to see where you might fit in that branch of the family. Because trust me, you do fit – somehow, someplace.

Cost

Genetic Affairs uses a “credit” payment system. Your first 200 credits are free so you can learn. These may last you for weeks or months, depending on how often you run the clusters. If you manage multiple kits, you’ll use credits more quickly, but it’s worth every last dollar. Genetic Affairs is very inexpensive. I manage multiple accounts and I spend around $5 per month. You can read about Genetic Affairs’ payment plans and see sample calculations here.

My recommendation is simply to dive in and use your free credits. By the way, I’m gifting myself with a “credit purchase” for Christmas😊

Genetic Affairs is a wonderful genealogy gift idea for serious genealogists, adoptees or people seeking unknown parents or ancestors in recent generations.

Have You Tested or Transferred With All 4 Vendors?

If you haven’t yet tested at or transferred to each of the main 4 vendors, clustering, reconstructed trees and SuperClusters is yet another reason to do so. Additionally, every close relative’s DNA holds hints that yours doesn’t, so be sure to test them too.

You can purchase kits, below, or read about how to transfer your DNA to vendors who accept uploads – FamilyTreeDNA, MyHeritage and GedMatch, all for free, here.

Enjoy!

Making Sense of Ethnicity Updates

In the last few days, Ancestry completed a rollout of an ethnicity update. For many customers, this is the first update since they tested – and the shocked, surprised, happy and unhappy commentary began immediately.

I’m receiving a lot of questions, including people who are doubting paternity based on  ethnicity. In a word – DON’T.

Ethnicity is the tool that encouraged many people to test via ads promising to tell you who you are. Consumers perhaps had unrealistic expectations about their results.

I was seriously upset when Ancestry posted my first ethnicity results in 2012 stating that I had 12% Scandinavian, when I don’t have any. 12% isn’t “noise,” it’s equivalent to one great-grandparent – and I know who all of my great-grandparents are, confirmed by DNA, and where they were. No Scandinavians among them.

Make no mistake, I used to get excited, upset, or both. I was outraged in 2012, here, but not any longer. I’ve adjusted my expectations.

I understand what’s really going on, meaning that ethnicity is a great feel-good sales tool (queue up the music), but does not have the ability to predict ethnicity accurately beyond the continental level (Europe, Africa, Asia), plus Native American and Jewish.

New Results

Companies continually try to refine ethnicity estimates by:

  • adding reference populations
  • mining their own customer data
  • taking advantage of academic research that may provide more and better tools

Consumers crave country or region-level specificity, but the technology today can’t deliver that, and maybe never will.

I discussed this in the article, Ethnicity is Just an Estimate – Yes Really!, which I illustrated by showing states in the US overlayed over Europe. No one would expect a company to be able to tell the difference between Indiana and Illinois residents, but for some reason, we expect differentiation between Germany and France. Or maybe we’re just hopeful!

Ethnicity states over Europe

That said, here is the graphic of my new Ancestry ethnicity results.

Ancestry ethnicity 2019.png

Along with the percentages.

Ancestry ethnicity percents 2019.png

I remember the first time I received an ethnicity result. I was INCREDIBLY excited – even though it turned out to be highly inaccurate.

Now, as then, ethnicity is ONLY AN ESTIMATE.

Let me say that again.

ETHNICITY IS ONLY AN ESTIMATE

Your ethnicity percentages at all the vendors are going to change, sometimes for the “better” and sometimes for the “worse.”

Of course, better and worse are terms defined by every person individually based on family stories, research or even just perceptions.

How Can You Determine Accuracy?

Years ago, I assembled a chart of what my expected ethnicity would be based on my known and proven family tree. You can read about how I did that in conjunction with my search for my Native American heritage in the article Revealing American Indian and Minority Heritage Using Y-line, Mitochondrial, Autosomal and X Chromosomal Testing Data Combined with Pedigree Analysis.

Understand that while each person inherits half of their DNA from each parent – we don’t inherit exactly half of their ancestor’s DNA that our parents carry. We might get 20% from one grandparent and 30 from another – totaling the 50% of our DNA inherited from one parent. So population level DNA isn’t going to be passed down in equal chunks in every generation either – but determining where your ancestors are actually from is the first step in setting expectations realistically.

Of course, this only works for genealogists who have already invested time into creating and documenting a family tree.

Comparing Ethnicity

Comparing expected ethnicity to ethnicity estimates can be enlightening for everyone.

Here’s the chart I created showing various Ancestry updates beginning in 2012 through the current 2019 update, today. My “expected” percentage of DNA is shown in the Genealogy % column.

Ancestry ethnicity over the years.png

Note that my Scandinavian is “worse” at 15% than the original 2012 estimate at 12% – especially given that I have no Scandinavian ancestors. It had dropped to 0 in 2018.

The British Isles is about right. Western Europe is low, but if you combine Scandinavia with western Europe, that would be about right.

Ancestry vacillates back and forth on my Native. Now you see it, now you don’t. Those segments are proven through 23andMe’s ethnicity segment painting along with Y and mitochondrial DNA from those ancestral lines.

It’s worth noting that many companies provide ranges of DNA, with what’s expected to be the “most accurate” shown.

In a few days, I’ll share my results from all of the companies so you can take a look at the differences between companies.

Ok, so what now?

Ethnicity IS

  • Interesting
  • Fun
  • A great discussion at the holiday table (and much safer than politics)
  • An entry level test that will hopefully encourage at least some people to become interested in genealogy
  • Cousin-bait
  • Not to be taken terribly seriously, seriously
  • To be taken with a very large grain, up to the entire lick of salt
  • A wonderful way to introduce the topic of family stories to people who might not otherwise be interested
  • A great way to distinguish between continental level DNA, and matches, if you’re lucky enough to be admixed in this way
  • NEVER to be used to doubt parentage
  • To be viewed as an “entertainment value” test

Ethnicity IS NOT

  • Ever a reliable predictor of parentage
  • Confirmation of minority ancestry without additional research
  • Disproof of minority ancestry without additional research
  • A shortcut in lieu of genealogy research
  • A reason to dismiss, or believe, a family story

Ummm – About Parentage

Regarding parentage – ethnicity testing can’t tell you any more about your parentage that your eyes looking in a mirror. People with known Italian parents, for example, show no Italian ethnicity – even when the matches to their Italian family are confirmed.

If you have ethnicity from multiple continents, by the time you can no longer see that visually – the percentage is too low for ethnicity to be able to help you reliably. Keep in mind that we can visually see continental admixture at the 25% level, and Ancestry gave me 15% Scandinavian ethnicity which I don’t have in reality. That’s more than the expected 12.5% of a great-grandparent.

Also remember that we often see what we are looking for. If I look long enough and hard enough in the mirror, I could see those Vikings😊

Why Do the Companies Produce Ethnicity Estimates?

If these results need to be taken with a grain, or maybe a lick of salt, then why do the companies continue to produce ethnicity estimates?

  • Plain and simple, because consumers want them
  • Ethnicity sells DNA tests (have you seen those ads?)
  • Testers are enchanted with the results
  • Ethnicity results engage consumers, making more people want to test “just to see”
  • Ethnicity updates bring people back to sign in to their account and check their results again

For some companies, ethnicity is the gateway (drug) for selling subscriptions to search for those ancestors whose tales are told, or hinted at, through ethnicity results. Don’t think “gateway drug” like it’s a bad thing.

For all of us, ethnicity is a way for many people to stick their collective toes in the genealogy water – in a place where we can see that they exist. Even if they never create a tree or answer a message – for some, who can figure out who they are – just the fact that they are IN the data base helps us to place other matches accurately.

There’s always hope that we can introduce ethnicity testers to the wonderful world of genealogy. I always offer to share. I was a beginner once too, as we all were.

Testing

You can obtain ethnicity results from any of the major testing vendors, including:

You can also transfer your DNA to GedMatch to obtain other estimates using their admix tools.

Instructions for downloading your files from the vendors in order to transfer can be found here.
