If you have a The Cohen Modal Haplotype badge in the Badges section of your dashboard, it means that you match or are close to the historic Cohen Modal Haplotype (CMH). One of the earliest Y-chromosome population genetics studies documented [...]
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 [...]
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. [...]
All of our kits go through the same basic process once we have the sample in our lab. Here are some of our most common questions about your test status and what we do with your sample. [...]
You will find answers to our most common questions on this page. Explore the rest of the Learning Center to find answers to more complicated issues by clicking the menu bar above. Before I Buy You may learn more [...]
Just as there are surnames that are very common (such as Smith and Jones) and surnames that are uncommon, there are Haplotypes (a set of results that characterize you on the Y-chromosome) with a high frequency of occurrence (aka common) and [...]
Your direct paternal lineage is the line that follows your father’s paternal ancestry. This line consists entirely of men. Y-DNA follows the direct paternal line. Your Y-chromosome DNA (Y-DNA) can trace your father, his father, his father’s father, [...]
FamilyTreeDNA is an online service. Therefore, all results provided by FamilyTreeDNA will only be available online and accessible via a computer or mobile device with internet capabilities. Results will not be mailed, and we will not issue refunds for tests [...]
A "Relevant Match" as stated in the Family Tree DNA release form is one of the following: Relevant Matches Test Genetic Distance of Relevant Matches Y-DNA 12 Exact Matches and (within a project) a genetic distance of 1 Y-DNA 25 Genetic distances [...]
Group Project members have the ability to assign access levels for their Group Project Administrators and Co-Administrators. Assigned on the member's Project Preferences page, these access levels determine what member information an administrator can view and in some cases, modify. The following [...]
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 [...]
A Y-DNA SNP test determines your Y-DNA haplogroup. Knowing how you connect to other people on the Y-tree can help narrow geographical origins and can potentially confirm specific genealogical connections. We encourage you to test as many SNPs as possible for [...]
Al Aburto is a member of the genetic genealogy community and a group project administrator. He became involved in genetic genealogy in 2005. He is retired and lives with his wife in Southern California. Apart from genealogy, they are involved [...]
Eugen Hartmann joined the genetic genealogy community in 2009. He is the group project administrator of two geographic projects. Both focus on those of German descent. He lives and works in Russia with his family. Eugen Hartmann Rebekah: [...]
In genetic genealogy, Dr. Ken Nordtvedt is one of the icons of early Y-DNA Haplogroup origins research. His earliest work was in sub-grouping Y-DNA Haplogroup I using STR marker based clusters. A resident of Montana, Ken lives with his wife. [...]
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 [...]
Tim Janzen is a community leader in using autosomal DNA (what we inherit equally from both parents) to trace and affirm family connections. With an extensive background in traditional genealogy and especially Mennonite genealogy, Tim has lead efforts to develop [...]
Matthew Dexter is an active member of both his home community and of our genetic genealogy community. At home, he is a dedicated church member who is currently helping them install a new video and sound system. In the community, [...]
FamilyTreeDNA and Sorenson Labs use different standards to report four STR (short tandem repeat) marker values. After you transfer your results, we convert them to FamilyTreeDNA's standard. The four markers that will change are DYS441, DYS442, Y-GATA-A10, and Y-GATA-H4.
