Autosomal DNA tests utilize DNA from the 22 pairs of autosomal chromosomes. Autosomal DNA is inherited from both parents. Therefore, an autosomal DNA test may be taken by either a male or a female. Autosomal DNA Inheritance 1 2 3 [...]

The Family Finder - Family Matching feature allows you to view your confirmed maternal and paternal Family Finder matches at a glance and separately. This feature assigns maternal or paternal icons to a customer’s Family Finder - Matches list based on phased matching [...]
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 Family Finder - Downloads page allows you to download files of your raw results and your Family Finder matches. Files in .CSV or .XML format can be opened using a spreadsheet program such as Excel. GZIP files can be extracted [...]
No. The Family Finder software does not use mitochondrial DNA results for matching or relatedness calculations. The Family Finder program uses only the autosomal SNP (single nucleotide polymorphism) test results from the Family Finder microarray chip.
No. The Family Finder software does not use Y-chromosome DNA (Y-DNA) results for matching or relatedness calculations. The Family Finder program uses only the autosomal SNP (single nucleotide polymorphism) test results from the Family Finder microarray chip.
No. The Family Finder test does not currently use X-chromosome DNA (X-DNA) test results for matching purposes. The X chromosome follows a different inheritance pattern than the rest of your autosomal DNA. Therefore, it requires a different matching algorithm to be [...]
If your Y-chromosome DNA (Y-DNA) match is not on your Family Finder match list, it may be that the match did not take the Family Finder test. Matches do not work across databases. You may check this on your Y-DNA match [...]
I have a close match. We cannot find any common names or ancestors on my Family Finder match list. Why can’t we?
It is both possible and reasonable for you not to have matches in common with a close cousin. For example, your relationship with your close cousin may be through your mother. However, your relationship to the majority of your matches [...]
I used a third-party tool to analyze my and a relative’s results. They are different from my Family Finder results. Why is this?
When you compare two people's Family Finder results using third-party tools, it is common for there to be small differences. The FamilyTreeDNA Family Finder program uses a proprietary set of calculations to evaluate shared DNA segments and to determine relationships. [...]
Our autosomal test is known as Family Finder. This test is designed to find relatives on any of your ancestral lines within the last five generations. Family Finder uses autosomal DNA, which is the mixture of DNA you received from both [...]
No. The Family Finder test is not a legal paternity test. The Family Finder test is not AABB accredited and cannot be used in a court of law for paternity purposes. If you are interested in a legal AABB accredited test, [...]
Family Finder raw results files are comma-separated-variable (CSV) files. We compress them into GZ (zipped) files for storage and portability. To extract the CSV file from the GZ file, you will need compression/decompression software to unzip the file. Many such [...]
How do my Family Finder match and I know on which line the connection took place? How can I tell on which side my matches are related (mother or father)?
It is not possible to tell from your Family Finder results if a match is from your mother's side or your father's side. This is because autosomal DNA recombines each generation. With an autosomal genetic test, the only sure way [...]
You may read about the responsibilities of a Family Tree DNA Project administrator in the GAP Guidelines.
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 [...]
Will Family Finder Project members be able to see their analytic data? Will they rely on me for all interpretation?
Part of your responsibility as a project administrator is to interpret the genetic relationships between project members in light of traditional genealogical records. Members of your Family Finder Project will see their own matching results. They will be displayed in [...]
We will send an email notification for any new Family Finder matches determined to be Immediate or Close matches. We do not send notifications for Family Finder matches that are more distant than 2nd cousin. Note that you may see new [...]
The Family Finder test traces all of your ancestral lines. It uses your autosomal DNA to identify relationships going back roughly five generations. This is different from our mitochondrial DNA (mtDNA) and Y-chromosome DNA (Y-DNA) tests. They trace clearly and exclusively [...]
