Haplogroup IJK

Haplogroup IJK
Possible time of origin	47,000-60,000 (haplogroup K2-m526 has been found in Ust Ishim meaning the IJK must be significantly older that 45kya [1].
Possible place of origin	Southwest Asia
Ancestor	Haplogroup HIJK
Descendants	IJ, K
Defining mutations	L15/S137, L16/S138, L69.1(=G)/S163.1

Haplogroup IJK is a human Y-chromosome DNA haplogroup. IJK is a primary branch of the macrohaplogroup HIJK. Its direct descendants are Haplogroup IJ and Haplogroup K.

Distribution and structure

The basal paragroup HIJK* has not been identified in living males or ancient remains.

Populations with high proportions of males who belong to descendant major haplogroups of Haplogroup HIJK live across widely dispersed areas and populations. Subclades of IJK are now concentrated in males native to:

• Europe (e. g. haplogroups I, J, R and N);
• the Middle East and North East Africa (e. g. haplogroups J and T);
• South Asia (e.g. haplogroups K, L and R);
• South East Asia and the Pacific (e. g. haplogroups K, M, O, P, S)
• Northern Eurasia, e. g. haplogroups N and Q) and;
• Native American peoples (e. g. haplogroup Q).
