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 J, L and R);
- East Asia，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 and R).
† = A basal haplogroup that has not been documented among living individuals.
(Based on the YCC 2008 tree and subsequent published research.)
The defining SNP L16 is at location rs9786714 with the ancestral value being G and the derived value being A.

- The remains of Ust'-Ishim man, dating from 45,000 BP have been found to be NO*, meaning that IJK must be significantly older.
