You can add your DNA matches to your personal family tree with the myFamilyTree tool from FamilyTreeDNA. Whether or not you are just starting to build your tree or already have a GEDCOM file uploaded into your kit, this feature is designed to enrich the total [...]
You should test more Y-Chromosome DNA (Y-DNA) STR (short tandem repeat) markers when you want to compare additional markers against others with similar results. Our motto could be: Test only what you need, and upgrade only when necessary. Time to [...]
We offer three basic types of tests: Family Finder (autosomal DNA), Y-DNA, and mitochondrial DNA (mtDNA). Note: Click on the blue boxes () below for information on each topic. Our Family Finder test focuses on autosomal DNA, which is inherited from both your mother [...]
A Y-DNA test looks at male inherited Y-Chromosome DNA. As the Y-Chromosome is passed on from a father to his sons, it is only found in males. Y-DNA testing can then be used to trace clearly a direct paternal line. [...]
The Y-DNA - Haplotree displays your Y-DNA haplogroup information and branches, your home branch, and your Y-DNA SNP (pronounced as snip) results. To access your Y-DNA - Haplotree page: Sign in to your myFTDNA account. On the navigation bar at [...]
Your direct maternal lineage is the line that follows your mother’s maternal ancestry. This line consists entirely of women, even though both men and women have their mother’s mitochondrial DNA (mtDNA). This means that fathers do not pass on their mtDNA to [...]
The Chromosome Browser is a feature of our Family Finder autosomal DNA test. This tool allows you to view and compare the DNA segments that you share with your Family Finder matches. Click image for a closer look. [...]
Y-DNA - Standard Y-STR Values shows the results of standard Y-DNA short tandem repeat (STR) tests: Y-DNA12, Y-DNA25, Y-DNA37, Y-DNA67, Y-DNA111, and Big Y. The following are descriptions of special characters that you might see on your results page: ¤ This result is new since [...]
Please note that as of January 30, 2019 the Big Y-700 test is now available, and the Big Y-500 test is no longer available for purchase. The Big Y is a Y-chromosome direct paternal line test. We have designed it to explore deep ancestral links on [...]
The Genealogy page is where you can add surname and earliest known ancestor information. To access your Genealogy page: Sign in to your myFTDNA account. In the upper-right corner of the page, hover your cursor over your name/Kit No., and click Account Settings from the [...]
The Privacy & Sharing page is where you can opt in to matching and view and specify your preferences regarding what information you share and with whom you share it. Note: On your Privacy & Sharing page, you can click the icon in each section for more information. [...]
This is your complete mitochondrial DNA. The complete mitochondrial genome consists of a single circular DNA sequence that contains 16,569 base pairs. The FamilyTreeDNA FMS test is called the mtFull Sequence test. This test will return results for all three parts of your mitochondrial [...]
A person who matches you on the X chromosome.
Family Finder - Matches lists your autosomal DNA matches. The top section of the page allows you to filter your matches; the bottom section displays your Family Finder matches. If you wish to download your matches, use the CSV button or Excel button at [...]
The revised Cambridge Reference Sequence (rCRS) is the revised sequence based on the first mtDNA sequence completed (Cambridge Reference Sequence).
Blaine Bettinger was one of the earliest to have a blog, The Genetic Genealogist, dedicated to using DNA for genealogy and personal ancestry. When I began using DNA testing for my personal genealogy research in 2005, I read his posts as part [...]
The centiMorgan (cM) values for DNA segments are measurements of how likely the segment is to recombine as it passes from parent to child. Segments with higher cM values have a greater probability of recombining in any one generation. Therefore, [...]
The Family Tree DNA bioinformatics team works with centiMorgan (cM) data from the International HapMap project. Current knowledge of centiMorgan values across the human genome comes from the International HapMap project testing. The project tested father-mother-child trios from global population [...]
Yes. Limitations in the number of global populations used and the number of samples tested in the International HapMap recombination rate studies limit what we know. SNP values at 12 locations in sequence Mother G A T A G A [...]
