CT Haplogroup

 

 

CT Haplogroup (P9.1, M168, M294) is a Y-chromosome Haplogroup. Haplogroup CT contains the M168 change, which is present in all Y-chromosome Haplogroups except A and B and is therefore the common ancestral type of all early migration out of Africa according to the Single origin hypothesis. The mutation is believed to have occurred 60,000 years before present in East Africa in a man dubbed Y Chromosomal Adam.


 

The defining mutations separating CT (all Haplogroups excepting A and B) are P9.1, M168 and M294. These mutations pre-date the "Out of Africa" migration. The defining mutations of DE probably occurred in Northeastern Africa some 65,000 years ago. The M130 and M216 mutations that distinguish Haplogroup C from all other descendants of CR may have occurred somewhat later, perhaps even as early as 48,500 years ago, after the first Out of Africa migration brought Homo sapiens to the southern coast of Southwest Asia.

The 21 Subclades for CT include;

Haplogroup CF, C, C1, C2, C3, C4, C5, F, DE, D, D1, D2, D3, E, E1, E1a, E1b, E1b1, E1b1a, E1b1b, and E2
