Big Y-700​

Explore your father’s line in greater
depth with the world’s most
comprehensive Y-DNA test.

$449USD

Surnames and historical records only reach back so far, but your paternal haplogroup has been passed down via DNA from father to son for thousands of years. The Big Y test unlocks the most specific Y-DNA haplogroup possible, finding the connections you need to uncover the origins of your father’s line.

WHY BIG Y?

Reaches beyond the barrier of surnames

WHO CAN USE THE BIG Y?

Designed for the genealogy enthusiast

If you are a genetic male...

If you are a <span style="color: #047ac1;">genetic male...</span>
The Y chromosome is passed down from father to son. Therefore, if you are a genetic male, you can take a Big Y test and research your paternal line.
If you are a genetic female...

If you are a <span style="color: #e0004d;">genetic female...</span>
Genetic females cannot take a Y-DNA test because they do not have a Y chromosome. However, if you are interested in learning about your paternal line’s ancestry, we recommend finding a genetic male to test—like a brother, uncle, father, or cousin.

Automatic updates to your haplogroup as our database grows

As our database grows, the branches on your Y-DNA haplotree gain more definition. Researchers can be more specific in identifying the descendants of a particular ancestor and in determining the time to most recent common ancestor (TMRCA).

COMPARE PRIVATE VARIANTS

Big Y SNP Matches

Private SNPs, or variants, are changes in genetic code that have not yet been found in other testers. Once someone with that variant tests, those private SNPs become new branches on the haplotree and a closer connection to explore. Use private variants to determine when surname lines branched off and to identify the TMRCA between you and your matches.
