Haplogroup IJK (Y-DNA)

Haplogroup IJK
Possible time of origin	40,000-45,000 years BP
Possible place of origin	Southwest Asia
Ancestor	Haplogroup F
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. 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]
