In human genetics, Haplogroup IJK is a human Y-chromosome DNA haplogroup. Haplogroup IJK is a descendant branch of the macrohaplogroup F with haplogroup IJ and haplogroup K as its attested descendants.[1]

According to Family Tree DNA, the two SNPs defining this haplogroup unite I, J, and K within F as a "brother clade" to G and H.[1] FTDNA further states that haplogroup IJK's relationship with haplogroup F1 through F4 is unknown.[1]

Distribution

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)
      • K (M9, P128, P131, P132)

Some of the main branches within the group are shown below:-

Haplogroup IJK
Haplogroup IJ
Haplogroup K
Haplogroup LT

Haplogroup L. South Asia.

Haplogroup T. Found in the Near East and parts of Africa, among the Ethiopians, Somalis, and Upper Egyptians. Fulbe carry the highest percentage at 18. Also found in small amounts in India and Eurasia.
