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

  • Link your recent genealogy with ancestors who lived before the adoption of surnames by discovering connections to others with similar and different surnames.
  • Estimate the time to most recent common ancestor (TMRCA) between you and your matches.
  • Confirm and refine your Y-DNA haplogroup, the origins of a group of people whose ancestry is traced back to a common ancestor on your paternal line.
  • Identify your family’s unique Y-chromosome mutations, known as SNPs.
  • Receive lifetime analysis.
  • Contribute to scientific advancements and help further grow the Y-DNA Tree of Humankind.

WHO CAN USE THE BIG Y?

Designed for the genealogy enthusiast

If you are a genetic male...
keyboard_arrow_down
keyboard_arrow_up
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...

keyboard_arrow_up
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.

VISUALIZE YOUR HAPLOGROUP’S EVOLUTIONARY HISTORY

Big Y Block Tree Matching Tool

The Big Y Block Tree makes it easier to understand how you and your matches’ paternal lineages relate to each other.

Discover details like:

  • The distribution of your matches based on their haplogroup and the country flags of their earliest known ancestor.
  • SNPs unique to specific surname lines to identify where and when surname lines branched off.
CLAIM YOUR PLACE ON THE TREE

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.
