In human genetics, Haplogroup D (M174) is a Y-chromosome haplogroup. Both D and E lineages also exhibit the single-nucleotide polymorphism M168 which is present in all Y-chromosome haplogroups except A and B, as well as the YAP unique-event polymorphism, which is unique to Haplogroup DE.
Haplogroup D is believed to have originated in Asia some 60,000 years before present. While haplogroup D along with haplogroup E contains the distinctive YAP pol...

In human genetics, Haplogroup D (M174) is a Y-chromosome haplogroup. Both D and E lineages also exhibit the single-nucleotide polymorphism M168 which is present in all Y-chromosome haplogroups except A and B, as well as the YAP unique-event polymorphism, which is unique to Haplogroup DE.
Haplogroup D is believed to have originated in Asia some 60,000 years before present. While haplogroup D along with haplogroup E contains the distinctive YAP polymorphism (which indicates their common ancestry), no haplogroup D chromosomes have been found anywhere outside of Asia.
Like haplogroup C, D is believed to represent the Great Coastal Migration along southern Asia, from Arabia to Southeast Asia and thence northward to populate East Asia. It is found today at high frequency among populations in Tibet, the Japanese archipelago, and the Andaman Islands, though curiously not in India. The Ainu of Japan and the Jarawa and Onge of the Andaman Islands are notable for possessing almost exclusively...
