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 .
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.^[1]

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).

Haplogroup A0-T is also known as A0'1'2'3'4. Haplogroup A1 is also known as A1'2'3'4. Haplogroup LT (L298/P326) is also known as Haplogroup K1. Between 2002 and 2008, Haplogroup T (M184) was known as "Haplogroup K2" – that name has since been re-assigned to K-M526, the sibling of Haplogroup LT. Haplogroup NO (M214) is also known as Haplogroup K2a (although the present Haplogroup K2e was also previously known as "K2a"). Haplogroup K2b (M1221/P331/PF5911) is also known as Haplogroup MPS. Haplogroup K2e (K-M147) was previously known as "Haplogroup X" and "K2a" (but is a sibling subclade of the present K2a, also known as Haplogroup NO). Haplogroup K2b1 (P397/P399) is similar to the former Haplogroup MS, but has a broader and more complex internal structure. Haplogroup K2b1a has also been known as Haplogroup S-P405. Haplogroup S (S-M230), also known as K2b1a4, was previously known as Haplogroup K5.
