Haplogroup K-M9

This article is about the human Y-DNA haplogroup. For the human mtDNA haplogroup, see Haplogroup K (mtDNA).

Haplogroup K or K-M9 is a genetic lineage within human Y-chromosome DNA haplogroup. A sublineage of haplogroup IJK, K-M9, and its descendant clades represent a geographically widespread and diverse haplogroup. The lineages have long been found among males on every continent except Antarctica.

The direct descendants of Haplogroup K1 (L298 = P326, also known as LT) and K-M9 are Haplogroup K2 (formerly KxLT; K-M526).[4][5]
