The Big Y product is a direct paternal lineage test. We have designed it to explore deep ancestral links on our common paternal tree. It tests both thousands of known branch markers and millions of places where there may be new branch markers. We intend it for expert users with an interest in advancing science.

Big Y – Results

The Big Y – Results page contains the following tabs and buttons:

Tabs

  • Known SNPs – Displays your single nucleotide polymorphisms (SNPs) that are on the list of ~36,000 known SNPs against which Big Y data is compared.
  • Novel Varients - Displays your SNP markers that are not on the list of ~36,000 known SNPs. These markers may or may not be unique to you as an individual. Men in related lineages may share some novel variants. As men from distantly related lineages test, SNP markers may be moved from the Novel Variants to Known SNPs.
  • Matching – Displays Big Y matches. A person is considered a match if they have four or less differences in SNPs with you.

Note: In the list above, click on the name of a tab to navigate to a complete explanation of that tab.
