2 unusual facts about Haplogroup O-P31


Haplogroup O-P31

Like all clades of Haplogroup O-M175, Haplogroup O-P31 is found only among the males of modern Eastern Eurasian populations.

One of these subclades, Haplogroup O-M95, is found among some (mostly tribal) populations of South and Southeast Asia, as well as among the Khmers of Cambodia and the Balinese of Indonesia.


Haplogroup O-M122

Another brother clade, Haplogroup O-P31, has an impressive extent of dispersal, as it is found among the males of populations as widely separated as the Kolarians of India and the Japanese of Japan; however, Haplogroup O-P31's distribution is much more patchy, and the Haplogroup O-P31 Y-chromosomes found among the Mundas and the Japanese belong to distinct subclades.

In a paper published in 2012, O3*-M122(xO3a-P200) Y-DNA was found in 12% (3/25) of a sample of Lao males from Luang Prabang, Laos.

Haplogroup O-M95

Patrilines within Haplogroup O-M95 predominate among the Austroasiatic-speaking populations of South and Southeast Asia, such as the Khmer of Cambodia and the Khasi of Meghalaya in northeastern India.
