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

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[edit]

Tree[edit]

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)
      • K (M9, P128, P131, P132)
