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

In human genetics, Haplogroup IJK is a human Y-chromosome DNA haplogroup. IJK is a descendant branch of the macrohaplogroup GHIJK and, subsequently, HIJK. Its direct descendants are Haplogroup IJ and Haplogroup K.^[1]

Subclades

Tree

This phylogenetic tree of haplogroup subclades is based on the YCC 2008 tree^[2] and subsequent published research.

• IJK
  • IJK (L15/S137, L16/S138, L69.1(=G)/S163.1)
    • IJ (M429/P125, P123, P124, P126, P127, P129, P130, S2, S22)

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. 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 similiar to the former Haplogroup MS, but has a broader and more complex internal structure. Haplogroup S (S-M230) was previously known as Haplogroup K5.
