We’re going to do three things in this article. Updating Your DNA Master Spreadsheet With New Matches Labeling Known Pileup Areas Utilizing Phased Family Finder Matches You must do item one above, before you can do item three…just in case … Continue reading
This article covers both sorting in Excel and how to identify an overlapping segment, and what that means to you as a genetic genealogist. I swore I wasn’t going to teach Excel, but there have been so many questions about … Continue reading
Today, we’re going to talk about the concepts of autosomal DNA and the differences between: Match groups Mathematical triangulation Genealogical triangulation Match Groups At Family Tree DNA, when you download your chromosome matching results, meaning your complete spreadsheet, then sorting into chromosome order (sort … Continue reading
One of the ways people utilize autosomal DNA for genealogical matching is by looking for common segments of DNA that match with known, or unknown, relatives. When the relationship to the person is unknown, we attempt to utilize how much DNA … Continue reading
At Family Tree DNA, your Y DNA and full sequence mitochondrial matches display a column titled Genetic Distance. One of the most common questions I receive is how to interpret genetic distance. Many people mistakenly assume that genetic distance is the number of … Continue reading
Lots of people have struggled with exactly how to identify and work with autosomal DNA matches, create DNA match groups and triangulation groups, which isn’t at all the same thing. Add to that multiple testing vendors who provide you with different types information … Continue reading
In the new Concepts series titled Managing Autosomal DNA Matches, we’re going to be working with your DNA information from several sources. In order to create matching spreadsheets, you’ll need to download your autosomal information from Family Tree DNA. Sign … Continue reading
Recently, I received a question about exactly how and why we can use Y DNA to identify or connect with a patrilineal ancestor. “I do not quite understand how the profiles can be identified specifically to an ancestor since that … Continue reading
I recently used a technique called parental phasing as part of the proof that one Curtis Lore found in Pennsylvania was the same person as Curtis Benjamin Lore, found later in Indiana. Given that I’ve already used parental phasing as part of a … Continue reading
In autosomal DNA testing, you’ll see the terms centiMorgans, represented as cM and SNPs, which stands for single nucleotide polymorphism, combined. These are two terms that are used to discuss thresholds and measurements of matching amounts of autosomal DNA segments. … Continue reading
