Haplogroup K2b1, known sometimes as haplogroup MS, is a human Y-DNA haplogroup, defined by SNPs P397 and P399. It has a complex, diverse and not-yet fully understood internal structure; its downstream descendants include the major haplogroups Haplogroup M (P256) and Haplogroup S (M230).[3][2]
It is not clear at present whether the basal paragroup K2b1* is carried by any living males. Individuals carrying subclades of K2b1 are found primarily among Papuan peoples, Micronesian peoples, indigenous Australians, and Polynesians.
