E1b1b1a

In human genetics, E-V68, also known as E1b1b1a, is a major Y chromosome haplogroup found in northeastern Africa, Western Asia and Europe, and is in turn part of the larger haplogroup known as E-M35. It is identified by the presence of a single nucleotide polymorphism (SNP) mutation on the Y chromosome known as V68. It is a subject of discussion and study in genetics as well as genetic genealogy, archaeology, and historical linguistics.
