Haplogroup P1 (Y-DNA) (original) (raw)

Haplogroup P1, also known as P-M45 and K2b2a, is a Y-chromosome DNA haplogroup in human genetics. Defined by the SNPs M45 and PF5962, P1 is a primary branch (subclade) of P (P-P295; K2b2). The only primary subclades of P1 are Haplogroup Q (Q-M242) and Haplogroup R (R-M207). These haplogroups now comprise most of the male lineages among Native Americans, Europeans, Central Asia and South Asia, among other parts of the world.
