Haplogroup P also known as
P-P295 and
K2b2 is a
Y-chromosome DNA haplogroup in
human genetics. P-P295 is a branch of
K2b (previously Haplogroup MPS; P331), which is a branch of
Haplogroup K2 (K-M526).
The only primary branches (clades) of P-P295 are
P1 (P-M45) and P2 (P-B253).
[1] P1 is, in turn, the parent node of
Haplogroup Q (Q-M242) and
Haplogroup R (R-M207).
The major subclades Haplogroups Q and R now include most males among
Europeans,
Native Americans,
South Asians and
Central Asians.
In a 2014 phylogenetic analysis of southeast Asian populations, the researchers Karafet, Mendez, and colleagues, say that their findings point to:
[3]
... an initial rapid diversification process of K-M526 that likely occurred in
Southeast Asia, with subsequent westward expansions of the ancestors of haplogroups
R and
Q.
