Haplogroup M (Y-DNA)

Haplogroup M (Y-DNA)

In human genetics, Haplogroup M (P256) is a Y-chromosome DNA haplogroup.

This haplogroup is found at various frequencies among populations of eastern Indonesia, Melanesia (including Papua New Guinea), Micronesia, and Polynesia. The majority of males from Papua New Guinea and Melanesia carry haplogroup M chromosomes.

It is a descendant haplogroup of haplogroup K, and is believed to have first appeared approximately 10,000 years ago.


The subclades of Haplogroup M with their defining mutation, according to Karafet et al (2008)

Note The 2008 paper introduced a number of changes, compared to the previous 2006 ISOGG tree Before the discovery of the P256 marker, the current subgroup M1 (defined by the M4 marker) previously represented the whole of Haplogroup M; and subgroups M2 and M3 were formerly classed as subgroups K1 and K7 of the parent Haplogroup K.
