When Bennett Greenspan couldn’t find a lab willing to compare his DNA with a potential cousin’s in Argentina, he decided to build one himself. That was 1999. The company he founded the following year — FamilyTreeDNA — became the first consumer genetic genealogy service in the world, and more than two decades later it remains the only major platform that offers all three types of genealogical DNA testing: autosomal, Y-DNA, and mitochondrial. That combination, and the deep research infrastructure built around it, is what sets FamilyTreeDNA apart from every other service on the market.
It is not, however, the right starting point for everyone. Understanding what FamilyTreeDNA does exceptionally well — and where it genuinely trails the mainstream alternatives — is essential to deciding whether it belongs in your research toolkit.
A Platform Built for the Specialist
FamilyTreeDNA was built from the ground up around a simple insight: different genealogical questions require different kinds of DNA evidence. Autosomal DNA can reveal relatives across all branches of your family tree going back roughly five or six generations. Y-DNA follows the direct paternal line — father to grandfather to great-grandfather — potentially across dozens of generations. Mitochondrial DNA does the same for the direct maternal line. No other consumer platform offers all three with the same depth of analysis and the same commitment to genealogical research over medical applications.
The company’s Houston laboratory is CLIA-certified and CAP-accredited, operated by Gene by Gene, now part of myDNA after a 2021 merger. That merger brought additional resources to FTDNA’s infrastructure without changing its core genealogical mission or its Houston-based operations.
The pioneer of the genetic genealogy industry, FamilyTreeDNA has helped over two million people break down genealogical brick walls. That figure spans three separate databases — autosomal, Y-DNA, and mitochondrial — which are distinct and differently sized. The autosomal database is considerably smaller than AncestryDNA’s, a meaningful practical disadvantage for cousin-matching. The Y-DNA and mtDNA databases, on the other hand, have no real competitors: FamilyTreeDNA is the only major DNA testing company that offers dedicated Y-DNA and mtDNA kits for genealogists.
The Test Lineup
Family Finder is FTDNA’s autosomal test — the equivalent of what AncestryDNA and 23andMe offer. It identifies relatives across all ancestral lines, provides an ethnicity estimate (myOrigins), and enables chromosome browsing and segment analysis tools that go considerably deeper than what AncestryDNA exposes to its users. The new myOrigins 3.0 includes 90 reference populations sourced from 8,053 individual samples, a substantial expansion that makes the ethnicity breakdowns considerably more granular than earlier versions. Family Finder also now bundles with myDNA Wellness, adding health and trait insights for those who want them alongside their genealogical results.
For researchers who have already tested at AncestryDNA or 23andMe, FTDNA offers an autosomal transfer program — uploading your raw DNA data from another platform to unlock basic matching in the FTDNA database for a small fee, without requiring a new kit.
Y-DNA testing is where FamilyTreeDNA has no peer. The platform offers STR panel tests at three levels (Y-37, Y-111, and higher) as well as the flagship Big Y-700, which sequences over 700 STR markers alongside hundreds of thousands of SNPs to produce the most precise Y-haplogroup placement currently available to consumers. Big Y-700 is the world’s most comprehensive Y-DNA test, and the results feed into FTDNA’s continuously updated haplogroup tree — a collaborative research infrastructure that benefits from every new tester added to the database.
For researchers working on a specific surname line, Y-DNA testing on FTDNA is often the only tool capable of definitively separating two families with the same name, confirming a suspected connection across a gap in the paper record, or identifying a non-paternity event buried several generations back.
Mitochondrial DNA (mtFull Sequence) tests the complete mitochondrial genome, providing the highest possible resolution for maternal-line research. FamilyTreeDNA’s mtDNA Tree of Humankind has expanded with 35,000 new branches, offering more detailed maternal ancestry insights than ever before. Full mitochondrial sequencing is a niche tool — useful primarily for confirming deep maternal haplogroup placement or identifying potential matches on a very specific ancestral line — but for researchers where that question matters, it remains uniquely available here.
What FamilyTreeDNA Does Better Than the Alternatives
Chromosome browser. Family Finder includes a full chromosome browser, allowing researchers to visualize which segments of DNA are shared with a given match and to identify which specific chromosomal regions appear across multiple relatives — a technique called segment triangulation that can powerfully confirm or refute hypothetical family connections. AncestryDNA does not offer a chromosome browser at all. MyHeritage does offer one, and it is a genuine strength of that platform — but FTDNA’s implementation is more mature, and the segment data it exposes integrates more cleanly with third-party tools like GEDmatch (covered separately in our GEDmatch article).
Segment data. FTDNA exposes the actual start and end positions of shared DNA segments, along with centimorgan values, which allows researchers to use third-party analysis tools more effectively. MyHeritage also provides segment data, making both platforms meaningfully more useful for advanced analysis than AncestryDNA or 23andMe.
Y-DNA and mtDNA depth. Living DNA includes Y-DNA and mitochondrial analysis as part of its standard autosomal kit — a genuine differentiator for that platform. But the depth of that analysis does not approach what FTDNA offers. Living DNA provides haplogroup placement and broad regional matching; FTDNA’s Big Y-700 sequences hundreds of thousands of SNP positions and feeds into a continuously updated haplogroup tree that has accumulated more than two decades of collaborative research. For anyone serious about paternal or maternal line research, the gap is substantial.
Surname and geography projects. FTDNA has hosted thousands of group research projects organized around surnames, haplogroups, and geographic origins since the early 2000s. No other platform offers anything comparable. These projects aggregate results from participants with shared research interests, allow administrators to spot patterns across multiple testers, and make the platform uniquely useful for collaborative genealogical research. The Dillman DNA Project — run by the Dillman Family Association — is hosted on FamilyTreeDNA at familytreedna.com/groups/dillman. The project is open to all male-descended Dillmans, using the Y chromosome which passes from father to son. Male Dillmans who have not yet joined are encouraged to test or transfer their results and join the project — every new participant strengthens the collective research.
Privacy controls. FTDNA allows users to opt out of law enforcement matching specifically, a nuanced position that separates it from platforms that either participate fully (GEDmatch) or refuse entirely (AncestryDNA, MyHeritage). Researchers who have privacy concerns can participate in genealogical matching without their profiles being searched in criminal investigations.
Transfer program. FTDNA accepts raw DNA uploads from AncestryDNA, 23andMe, MyHeritage, and Living DNA, allowing researchers who have already tested elsewhere to add FTDNA’s matching database to their results for a modest fee. Living DNA also accepts free uploads from the major platforms. AncestryDNA has never accepted transfers, and MyHeritage discontinued its upload program — making FTDNA and Living DNA the two primary destinations for researchers who want to extend the reach of a test they’ve already taken.
Where FamilyTreeDNA Falls Short
Autosomal database size. The Family Finder database is the most significant practical limitation of the platform. AncestryDNA has tens of millions of testers; 23andMe and MyHeritage are both larger than FTDNA’s roughly two million total across all test types. For cousin-matching on recent family connections, this gap is real and meaningful. A researcher who tests exclusively at FTDNA will miss matches that exist only in one of the larger databases — which is why the transfer program matters so much, and why serious researchers typically test at multiple platforms rather than choosing one.
Interface complexity. New users can find the platform overwhelming, particularly compared to the streamlined experience AncestryDNA or MyHeritage offer. FTDNA rewards investment — the more you understand about how DNA testing works, the more useful the platform becomes — but it is not a good starting point for someone who wants results with minimal effort. MyHeritage in particular has invested heavily in an accessible interface and automated tree-matching features that FTDNA does not attempt to replicate.
Ethnicity estimates. FTDNA’s myOrigins 3.0 is a significant improvement on earlier versions, but ethnicity estimation remains a secondary focus for the platform. AncestryDNA and MyHeritage both invest more heavily in this area and produce more widely recognized results. For researchers whose primary interest is ethnicity percentages rather than genealogical matching, FTDNA is not the obvious choice.
Pricing. FTDNA’s tests are priced in line with or above competitors for the basic autosomal kit, and the specialized Y-DNA and mtDNA tests represent a meaningful investment beyond that. Current pricing is listed at help.familytreedna.com and changes periodically, particularly during sales events. The platform does run regular promotions, so it is worth checking before purchasing at full price.
Who Should Test at FamilyTreeDNA
Anyone researching a specific surname line through the male line — including Dillman researchers — should strongly consider a Y-DNA test at FTDNA. There is no substitute for it on any other platform.
Researchers who want chromosome-level access to their autosomal matches will find FTDNA more useful than AncestryDNA for triangulation and segment analysis, even with a smaller database.
Anyone who has already tested elsewhere should consider uploading their raw DNA to FTDNA through the transfer program. The cost is minimal and adds FTDNA’s matching database to whatever results they already have.
Researchers who have hit a brick wall on a direct paternal or maternal line should look seriously at Y-DNA or mtDNA testing, respectively. These tests can reach back across genealogical gaps that autosomal DNA cannot bridge.
For Dillman researchers specifically, the combination of the DFA’s active Y-DNA project on FTDNA and the platform’s unmatched Y-DNA infrastructure makes FamilyTreeDNA a natural part of the research toolkit, used alongside rather than instead of the larger autosomal platforms.
The Bottom Line
FamilyTreeDNA is not for everyone, and it was never designed to be. It is a specialist’s tool built by and for people who take genealogical DNA research seriously. Its Y-DNA and mitochondrial testing capabilities are genuinely unmatched — Living DNA offers surface-level Y and mtDNA analysis, but nothing approaching the depth of FTDNA’s Big Y-700 and full mtDNA sequencing. Its autosomal offering is more powerful than AncestryDNA’s in analytical depth, comparable to MyHeritage’s in chromosome tools, and more advanced than 23andMe’s for serious research — even if it trails the larger platforms in raw database size. And its surname project infrastructure, including the Dillman DNA Project, gives collaborative researchers a home that no other platform offers.
For Dillman family researchers working to connect lines, confirm relationships across the Atlantic, or push their research further than the paper record allows, FamilyTreeDNA deserves a place in the toolkit.
