	Haplogroup K
Time of origin	35,000-40,000 years BP
Place of origin	Southwest Asia
Ancestor	IJK
Descendants	L, MNOPS, and T
Defining mutations	M9

In human genetics, Haplogroup K (M9) is a Human Y-chromosome DNA haplogroup. This haplogroup is a descendant of Haplogroup IJK. Its major descendant haplogroups are L (M20), MNOPS (rs2033003/M526), and T (M70). Haplogroups K1, K2, K3 and K4 are found only at low frequency in South Asia, the Malay Archipelago, Oceania, and Australia.

[edit] Origins

Y-DNA haplogroup K is an old lineage established approximately 40,000 years ago whose origins were probably in southwestern Asia. At present this group contains two distinct classes of subgroups: (1) major groups L to T (refer to the main tree at Y-DNA Haplogroup Tree) and (2) minor groups K* and K1 to K4 which do not have any of the SNPs defining the major groups. These groups are found at low frequencies in various parts of Africa, Eurasia, Australia and the South Pacific.[1]

[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.
