Haplogroup K2b1 (Y-DNA)
| Haplogroup K2b1 | |
|---|---|
| Possible time of origin | 30,000-40,000 |
| Possible place of origin | Southeast Asia; Oceania. |
| Ancestor | K2b (P331) |
| Descendants | S (K2b1a) and M (K2b1b) |
| Defining mutations | P397, P399 |
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).
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.
