Haplogroup P (Y-DNA)

In, Haplogroup P (M45) is a.

This haplogroup contains the patrilineal ancestors of most s and almost all of the. It also contains approximately one third to two thirds of the males among various populations of and.

Haplogroup P is a branch of (M9). It is believed to have arisen north of the, in , , or , approximately 35,000 to 40,000 years ago.

The descendant haplogroups of P include (M242) and  (M207).

Besides the typically European/South Asian Haplogroup R and South-Central Siberian/Native American Haplogroup Q, other patrilines derived from Haplogroup P-M45 are labeled for sake of convenience as Haplogroup P* and are reported to have been found at low to moderate frequency among modern populations of, , , and the. There is a conspicuous presence of Haplogroup P* on the in the  off the n coast of, which may be due to historical immigration of  from Central Asia. There have also been reports of Haplogroup P* from samples of, , and some populations of and , but it is not entirely clear whether these were truly Haplogroup P* or rather instances of a rare haplogroup derived from Haplogroup P, such as  or.
