DNA Tests Available at Family Tree DNA
Basic Autosomal Test
- Family Finder – an autosomal DNA test which “provides powerful interactive tools to help find your DNA matches, trace your lineage through time and determine family connections.” Click here for more information.
For male testers only:
- Y-37 – “check for specific markers on the Y chromosome.
37 markers is a good place to start and can confirm close relationships.” Examines 37 short tandem repeats (STRs) on the Y chromosome. Click here for more information.
- Y-67 – “If want to know more about your paternal line through matching or participate in any of our free Group Projects, you will want to start with a Y-67 test. ” Examines 67 short tandem repeats (STRs) on the Y chromosome. Click here for more information.
- Y-111 – “Of most benefit for those looking to confirm Y chromosome matching at our highest level between two living men. The difference between the tests is that we test more markers (STRs) which allows for more refined results. ” Examines 11 short tandem repeats (STRs) on the Y chromosome. Click here for more information.

For male and female testers:
- mtDNA Plus – “Examines two regions of mitochondrial DNA (HVR1 and HVR2). Identifies basic haplogroup and migration paths.” Click here for more information.
- mtFull Sequence – “Examines all regions of mitochondrial DNA. Identifies basic haplogroup and migration paths. More refined results for genealogical purposes.” Click here for more information.
About Family Tree DNA
“Family Tree DNA is a division of Gene by Gene, a commercial genetic testing company based in Houston, Texas and founded in 2000. Family Tree DNA offers analysis of autosomal DNA, Y-DNA, and mitochondrial DNA to individuals for genealogical purpose.” According to ISOGG, “It is the most popular company worldwide for Y-DNA and mitochondrial DNA, and the third most popular for autosomal DNA.” Click here for full description at Wikipedia.
Family Tree DNA and Genealogy Research
- Family Tree DNA has recently (April 2017) updated its MyOrigins 2.o reporting model with new reference populations. This may cause past Family Tree DNA testers to see changes in their results. “Seeing your results change does not mean that they were incorrect before, but rather, that with more research and the addition of more reference populations we are able to paint a clearer picture of your genetic tapestry. As our database grows, we are able to gain a better understanding of the unique genetic variation for each of our reference populations, and even add new reference populations to our existing regions we will share these advances with you and continue to refine your results.”
- Family Tree DNA uses Ancient Origins as part of its basic autosomal test (Family Finder). “This feature compares your autosomal DNA to DNA found at archaeological dig sites throughout the European continent.”
- The Family Finder Matching Tool requires the tester to upload basic family tree information and have at least one maternal and/or paternal link.

Family Tree DNA Accuracy
“The Family Finder’s relationship ranges cover most possible relationships between two people. It takes into account several factors. These include the total number of shared DNA segments (blocks) and the total number of centiMorgans (cM). For the immediate and close relationship ranges, this is highly accurate. The nature of autosomal DNA means that the expected values will vary more in the distant cousins range. This means that the ranges are wider, but they are still accurate within a given range. The speculative category is exactly that, speculative.”
