Discover your paternal ancestry

The world's largest Y-DNA database

The Y chromosome passes almost unchanged from father to son. Male ancestors carried their Y-DNA line along their migrations, allowing you to trace your paternal ancestry by using our advanced Y-DNA tests and the world's largest Y-DNA database.

Special sections on the Y chromosome determine a male's Y haplogroup, revealing the origins of his ancestors as evidenced by common DNA markers.

Discover Paternal Heritage

Trace your paternal migration

Follow the path of your male ancestors

Males can use Y-DNA to determine where their direct paternal ancestors came from, their locations in historic times and how they migrated throughout the world.

  • Explore your direct paternal line and geographic origins

  • Uncover your paternal heritage going back to Africa

  • Trace your male ancestors' ancient migration paths

Trace Paternal Line

With the world's largest Y-DNA database, our advanced male-specific Y-DNA tests can be used to trace your direct and distant paternal lineage.

More markers means more confidence

Our male-specific Y-DNA tests check for specific markers on the Y chromosome.
37 markers is a good place to start and can confirm close relationships.
Increase your marker count to 67 or 111 for even greater confidence!

Frequently Asked Questions

What is Y-DNA?

Y-DNA is what we call the sex chromosome “Y” that is passed from a father to his sons only, women do not receive a Y chromosome. Testing the Y chromosome allows for investigation into a male's paternal family line and can help identify surname lines, living relatives whose Y chromosome is similar to yours, and ancient migration routes your paternal ancestors may have taken.

What is a Haplogroup?

Every male individual who takes one of our Y-DNA tests will also receive their Y-DNA haplogroup. When humans left Africa tens of thousands of years ago, they departed in small groups that migrated into different parts of the world. Over many generations, each group developed distinct mutations allowing us to identify one from the other. We call these groups of mutations haplogroups, and they can tell us which migratory routes our paternal ancestors traveled.

What does SNP stand for?

Single nucleotide polymorphisms, frequently called SNPs (pronounced “snips”), are the most common type of genetic variations. Each SNP is a mutation or new branch on the tree. The number of SNPs on which people match within a database can be used to tell how closely related they are.

What is a Marker or STR?

A marker is what we test in our basic Y-DNA tests. These markers are also referred to as STRs (Short Tandem Repeats) which are a series of repeating nucleotides (A, T, G, C). For example: GACTACTACTACTGG - the STR consists of the three repeated CTA segments. Y-DNA tests look for matching markers or “STRs” between two men, if they match, which would indicate a genetic relationship.

Which test should I buy?

If you are looking to begin Y-DNA testing, the Y-37 Marker test will allow you to become familiar with Y-DNA results. However, 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. The Y-111 test will be 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.

I have questions about my Y-DNA test results. Where should I go?
