Haplogroup I-BY2776

What is Paternal Haplogroup I-BY2776?

Haplogroup I-BY2776, also known as Haplogroup I-M170 (Y Chromosome Consortium long-form label), is a genealogical group of lineages defined by unique genetic markers present on the Y-chromosome. Your paternal haplogroup, or that of your father if you do not have a Y-chromosome, paints a picture of your ancient origins and the migrations of your ancestors. Although your paternal haplogroup reflects just one of your many ancestral lineages, it carries information about that lineage over tens of thousands of years.

Haplogroup I-BY2776 is descended from haplogroup I-M170. Among 23andMe research participants, haplogroup I-BY2776 is commonly found among populations in the United Kingdom and Ireland.

It's important to note that your haplogroup doesn't define your current ethnic identity; rather, it provides an insight into your deep ancestry on the paternal side.
