Explore your father’s line in greater depth.
ONLY $399USD
Save $50 (was $449)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.

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.

GROUP PROJECTS
Big Y-700 Group Projects
- Y-DNA Geographical Projects: Studies how different groups of people interacted over time in a specific region of the world.
- Y Haplogroup Projects: Studies a specific branch of the Y-DNA Haplotree. This helps prove when different lines split apart and how modern-day test takers are related.
- Big Y and the Discover™ Group Time Tree: Public projects can use these powerful tools to visualize subgroups within the project and see how members relate to each other in historical time frames.
