Haplotype M3, accounted for 66% of male Y-chromosomes and was found associated with native populations from the Chukotka peninsula in Siberia, adjacent to Alaska. The second major group of Native American Y-chromosomes, haplotype M45, accounted for about one-quarter of male lineages. This haplotype was found in the Lower Amur River and Sea of Okhotsk regions of eastern Siberia. The remaining 5% of Native American Y-chromosomes were of haplotype RPS4Y-T, which was found in the Lower Amur River/Sea of Okhotsk region of Siberia. These data suggested that Native American male lineages were derived from two major Siberian migrations.¹
