Haplogroup BT (Y-DNA)

From Wikipedia, the free encyclopedia

In human genetics, Haplogroup BT, also known as Haplogroup YxA (SRY10831.1 (SRY1532), M42, M94, M139, M299) is a Y-chromosome haplogroup.

Haplogroup BT split off from haplogroup A 55,000 years bp, probably originating in North East Africa. It contains all living human Y-DNA haplogroups except for A.
