2025 has been quite a year in genetic genealogy. Genetic genealogy, per se, really isn’t a separate “thing” anymore. DNA testing is now an integral part of genealogy, with the potential to answer questions that nothing else can!
The 76 articles I wrote in 2025 fall into multiple categories and focus on different topics based on what was happening in the industry.
From my perspective, here are the most notable announcements and trends in genetic genealogy, and genealogy more broadly.
#1 for 2025 – Mitochondrial DNA: The Million Mito Project Released the New Mitotree, Updates, and mtDNA Discover
The biggest genealogy news items this year, both industry-wide and genealogy-changing are definitely the release of the new Mitotree, plus two tree updates. But that’s not all.
In addition, full sequence mitochondrial DNA testers received new Mitotree haplogroups, if appropriate, and everyone received a haplotype – a new feature. Along with Mitotree, FamilyTreeDNA introduced mtDNA Discover which provides 13 individual reports based on your haplogroup and matches.
It’s no wonder that mitochondrial DNA articles led the pack with the most views based on the eleven articles about that topic. If you haven’t yet tested your mitochondrial DNA at FamilyTreeDNA, there’s no better time! You never know what you’re going to discover and the more testers, the more matches for everyone.
You don’t know what you don’t know, and you’ll never know if you don’t test. Remember, mitochondrial DNA is for both males and females and tests your mother’s direct matrilineal line (mother to mother to mother, etc.) – reaching beyond known surnames. Click here to order or upgrade.
#2 – MyHeritage Low Pass Whole Genome Sequence Test Charges into the Future
Another big hitter is the new MyHeritage low-pass whole genome test (WGS) test. It’s new and innovative, but we haven’t seen comparative results yet.
My results from the new low-pass whole genome test just came back, and I haven’t had the opportunity to review them yet, as compared to the earlier tests. That said, I do have roughly the same number of matches, but I need to determine if they are the same matches, and how well they track. I’ll be working on that review soon.
The new whole genome test may be more about future proofing and preparedness than additional current benefit – but we will see. I definately wanted to take the whole genome test so I can receive and benefit from whatever new is coming down the pike.
MyHeritage allows you to maintain multiple DNA tests on your account, so the new whole genome won’t “replace” your older or uploaded test. That way, you can easily compare the results of the whole genome against any DNA test that you curently have at MyHeritage.

#3 – 23andMe Experiences Problems
On a less positive note, but still quite newsworthy is the bankruptcy of 23andMe and subsequent repurchase of 23andMe by the original founder after setting up a new nonprofit. I have real mixed feelings about this topic. However, 23andMe was really never about genealogy, and now, matching segment information is no longer available. Those searching for unknown parents or family may want to test there if they are unsuccessful elsewhere.
Best Genealogy Tool
The FamilySearch full text search continues to have a HUGE impact for genealogists. This tool is not one-and-done, but provides increasing amounts of rich information as more records are added to the “fully scanned” collection. If you haven’t tried it, please do. It’s a game-changer and continues to improve.
A Cautionary Word About AI – Artificial Intelligence
AI is such a hot topic right now that I feel it needs to be included.
The FamilySearch full text search uses a form of AI. However, you’ll quickly notice that it can’t read everything, gets words and names wrong, and if you actually need to fully depend on it for accuracy, you cannot. (That said, it’s still an amazing tool, and I’m not picking on FamilySearch.)
Aside from FamilySearch, AI in its current form is both wonderful and terrible. I’ll be writing about AI in the new year, but for now, don’t ever rely on AI for anything that you can’t verity. It’s your assistant, not an expert, no matter how insistent it is. Never trust and always verify.
This is ESPECIALLY TRUE WHEN RELATED TO GENETICS and genetic related topics. I can’t even begin to tell you how very wrong it has been, and how much people fall in love with inaccurate results. No, just no – at least for now.
You need to know your AI tool, your skill set, your understanding of AI broadly, the tool’s limitations, and yours, and that’s all before verifying the actual AI results. If you want to educate yourself, and everyone should, treat yourself to anything, anyplace by either Mark Thompson or Steve Little, the dynamic AI duo. They offer YouTube videos and classes in a wide variety of places – but keep in mind that AI tools and technology literally change every few weeks.
AI is, indeed, a specialty all unto itself, much like genetic genealogy. And right now, it’s not soup yet, but it is cooking.
Tried and True Genetic Genealogy Staples – DNAPrint and Genetic Affairs
I haven’t written about either one this year, but I use both DNAPainter and Genetic Affairs regularly.
I consistently paint segments from matches at both MyHeritage, FamilyTreeDNA, and GEDmatch that are newly identified to an ancestor or ancestral couple at DNAPainter.
Unfortunately, neither Ancestry nor 23andMe provide matching cM location information for your matches (chromosome browser), but you may find some people who have tested at those companies at both FamilyTreeDNA and GEDmatch if they have uploaded to either of those vendors. Both vendors provide segment information and a Chromosome Browser, enabling you to paint that information to DNAPainter when you can identify your common ancestor.
MyHeritage also provides a Chromosome Browser, but unfortunately, no longer accepts uploads from any other vendor. You can paint segments from MyHeritage, but no longer upload DNA files to MyHeritage.
Thanks to DNAPainter, I have 90% of my segments identified to specific ancestors – which is actually rather remarkable given that my mother’s grandfather was a Dutch immigrant, and her great-grandparents on her other side were German immigrants, meaning we don’t have many matches on either of those lines.
Genetic Affairs continues to develop new, advanced clustering tools, one of which I’ll be reviewing soon.
Major Vendor Releases
Aside from what’s listed above, most of the major vendors released new features.
MyHeritage released a VERY COOL new tool called Cousin Finder that finds your relatives in the MyHeritage database, whether they match you on a DNA test, or not. They may not have even taken a DNA test. Cousin Finder identifies your common ancestor and shows your relationships. It’s a wonderful way to initiate communications, discuss your common ancestors, and ask about DNA testing.
Of my 378 Cousin Finder matches, only 23 (about 6%) are on my DNA match list, so that leaves 355 people to message, several of whom represent Y-DNA and mtDNA lines I don’t have. You can bet I’ll be offering testing scholarships.
Additionally, MyHeritage released a new ethnicity version.
FamilyTreeDNA, in addition to the new Mitotree, Discover, and associated features, released a new match matrix so you can see if and how selected matches are related to each other in a grid format. In other words, you can create your own cluster.
A new built-in “Share” feature blurs private information to make sharing easier both on the website and in Discover.
Discover improvements include thousands of new Y-DNA and mtDNA tree branches, plus thousands of new Ancient DNA samples. Discover is evergreen, so once you’ve taken that Big Y-700 test or the mitochondrial DNA test, your learning never stops as more content is added.
Tree integration with WikiTree is super-easy and means you don’t have to choose between trees. You can choose to retain your archived tree at FamilyTreeDNA, or move your tree to MyHeritage, PLUS link yourself to your family at WikiTree.
Ancestry released match clustering and a new beta pedigree view of ThruLines, but that’s back in the shop for more work. I’d expect to see it rereleased in 2026.
Conferences
RootsTech is the granddaddy of genealogy conferences, and it’s always fun to attend and write about the experience. Many vendors release new tools or products during the conference.
The ECGGC (East Coast Genetic Genealogy Conference), held in the fall, is the only conference that focuses entirely on genetic genealogy, new tools, how to use existing tools, and more. The 2025 conference was virtual and provided a great deal of focused content. Attendees particularly appreciate the deep dive in a particular topic presented in DNA Academy.
I’ll be at RootsTech in 2026, will write about that soon, and hope to see you there.
Concepts, Techniques and Plain Old Genealogy
In the past, my Concepts series and genealogy “how to” articles have been very popular, so, in 2025, I penned a half-dozen articles focusing on frequently asked questions about relationships and DNA.
For example, how does one go about finding DNA testing candidates? The number of options may surprise you and includes both Cousin Finder and Relatives at RootsTech.
By testing ONE PERSON for either Y-DNA or mitochondrial DNA that represents an ancestor, you actually receive information about that entire lineage of ancestors. So, on my Estes line, by locating an Estes male from my line to test, I received relevant information for every Estes male in my line, back to and beyond the progenitor.
Eventually, we hit a brick wall in every line, and those tools are the perfect way to break through those brick walls.
Other articles discuss things like how to use Discover’s Ancient Connections, and the difference between half and full relationships, both in your tree and genetically. Plus, what does a cousin “once removed” mean anyway? And why do I care?
Another question I receive is how far back, based on the shared amount of DNA, should I look in my matches’ trees for our common ancestor? In other words, how many generations back should I click? That article was fun and produced some unexpected results.
Memorial Articles
Because we are part of a community, I write memorial articles when one of our friends passes on. This year, sadly, Schelly Talalay Dardashti, well-known Jewish genealogist, and another very close friend joined the ancestors, so I’ve recognized the best in both of their lives which constitutes their legacy.
Be the Storyteller
Last, but not least, I wrote about my ancestors in the “52 Ancestors” series, which launched several years ago with Amy Johnson Crow’s challenge to write about one ancestor per week. She hosts this every year, and you can join (free) now.
I’m now on ancestor #467, so yes, it’s addictive, but it’s also AMAZING how many wonderful cousins I’ve met who have information that I did not. Not only that, but after publishing about an ancestor, I’ve discovered that I’m related to people I’ve known for years. We were SOOOooo excited!
I’ve been writing about the lives of my ancestors for several years now, and the articles include attempts to identify Y-DNA and mtDNA testers for each ancestor, where appropriate. There’s so much to learn that can’t be revealed any other way.
Plus, people seem to like the “mystery” and “short story” aspect, and I salt each story with the history of the region and relevant historical events of the timeframe. You might find your ancestors here too, or other helpful information.
Find a way to share about your ancestors!
