Place of origin	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)
Defining mutations	M9

In human genetics, Haplogroup K (M9) is a Human Y-chromosome DNA haplogroup.

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.

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.

[edit] Subgroups

The subclades of Haplogroup K with their defining mutation, according to Karafet et al (2008) [1] (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 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.
