Haplogroup K (Y-DNA)

Infobox haplogroup
name =K


origin-date =40,000 years BP
origin-place =Iran or southern Central Asia
ancestor =F
descendants = L (M20), M (P256), NO (M214) (N and O), P (M45) (Q and R), S (M230) and T (M70)
mutations =M9In human genetics, Haplogroup K (M9) is a Human Y-chromosome DNA haplogroup. This haplogroup is a descendant of Haplogroup F (M89). Its major descendant haplogroups are L (M20), M (P256), NO (M214) (plus NO's descendants N and O), P (M45) (plus P's descendants Q and R), S (M230), and T (M70). Haplogroups K1, K2, K3 and K4 are found only at low frequency in the Indian subcontinent, Malay Archipelago, Oceania, and Australia.

Origins

It first appeared approximately 40,000 years ago in Iran or southern Central Asia. Today, haplogroup K and its descendant haplogroups are the patrilineal ancestors of most of the people living in the Northern Hemisphere, including most Europeans, Asians, and Native Americans. Other lineages derived from Haplogroup K are found among Melanesian populations, indicating an ancient link between most Eurasians and some populations of Oceania.

Subgroups

The subclades of Haplogroup K with their defining mutation, according to Karafet et al (2008) [http://www.genome.org/cgi/content/abstract/gr.7172008v1] (abbreviated for clarity to a maximum of five steps away from the root of Haplogroup K):

"Note" The 2008 paper made a number of changes compared to the previous [http://www.isogg.org/tree/ISOGG_HapgrpK.html 2006 ISOGG tree] . The former subgroups K2 and K5 were renamed Haplogroups T and S; the old subgroups K1 and K7 were re-assigned as new subgroups M2 and M3 of a redefined Haplogroup M; and the former subgroups K3, K4 and K6 were renamed to new K1, K2 and K3.
