FamilyTreeDNA is the pioneer and the world's most comprehensive DNA testing company in the new field of genetic genealogy.

If you are looking for that long-lost relative or ancestor, or if you feel that some day, someone may use a DNA repository to look for long-lost relatives, you should consider doing this simple DNA test.

Your ancestors left clues in your DNA which you can use to determine your deep ancestral origins and to link you with others in recent time. We can compare your results with our database - the largest of its kind in the world - and tell you whether those clues indicate possible Jewish ancestry and whether you match others who are Jewish. Our Jewish comparative databases are the largest in the world, containing records for Ashkenazim and Sephardim, as well as Levites and Cohanim.

Y-DNA:

Males can test their Y-DNA to determine the origin of their paternal line, including the possibility of Jewish and Cohanim ancestry. Note that the Y-DNA strictly checks the paternal line, with no influence from any females along that line. Females do not receive the Y-DNA, and therefore females cannot be tested for the paternal line. If you are a female and would like to know about your paternal line, you would need to have a brother or a male relative from that line to be tested.

mtDNA:

Both males and females can test their mtDNA to determine the origin of their maternal line. We compare your results with the data from the landmark study published by Dr. Doron Behar, our Chief mtDNA Scientist, and quoted by NY Times, CNN, BBC, and other major media outlets. Note that the mtDNA strictly checks the maternal line, with no influence from any males along that line. Both males and females receive the mtDNA from the mother.

Family Finder

For males and females. The Family Finder Test helps you find family across all your lines, up to 6 generations back, by checking hundreds of thousands of points in your autosomal DNA, and comparing your results with others in the Family Finder database.

DNA testing can show:

• if two people are related
• your suggested geographic origins
• if you could be of Jewish ancestry
• if you could be of Cohanim ancestry
• your deep ancestral ethnic origins
