Haplogroup B (M60) is a human Y-chromosome DNA haplogroup common to paternal lineages in Africa. It is a primary branch of the haplogroup BT.
B (M60) is common in parts of Africa, especially the tropical forests of West-Central Africa. It was the ancestral haplogroup of not only modern Pygmies like the Baka and Mbuti, but also Hadzabe from Tanzania, who often have been considered, in large part because of some typological features of their language, to be a remnant of Khoisan people in East Africa.
