Haplogroup BT (Y-DNA)

Haplogroup BT
Possible time of origin	70,000-80,000 years BP
Possible place of origin	Africa
Ancestor	A2-T
Descendants	B, CT
Defining mutations	Page65.1/SRY1532.1/SRY10831.1, M42, M91, M94, M139, M299, P97, V21, V29, V31, V59, V64, V102, V187, V202, V216, V235

In human genetics, Haplogroup BT (SRY10831.1 (SRY1532.1), M42, M94, M139, M299) is a Y-chromosome haplogroup. The notation BT refers to the derived set of haplogroups between B and T which forms its own cladistic set.

Haplogroup BT is descended from Haplogroup A2-T about 70,000 years bp, possibly originating in western North Africa or central West Africa. It contains the remaining living human Y-DNA haplogroups from macro-haplogroup A.
