From Wikipedia, the free encyclopedia

In human genetics, Haplogroup B (M60) is a Y-chromosome haplogroup.

Haplogroup B is localized to sub-Saharan Africa, espicially to tropical forests of West-Central Africa. After Y-haplogroup A, it is the second oldest and one of the most diverse human Y-haplogroups. It was the ancestral haplogroup of modern Pygmies like e.g. the Baka and Mbuti, but also Hadzabe from Tanzania, who are often mistakenly considered as a remnant of Khoisan people in East Africa.
