Haplogroup P (Y-DNA)

This article is about the human Y-DNA haplogroup. For the human mtDNA haplogroup, see Haplogroup P (mtDNA).

Haplogroup P (K2b2)
Possible time of origin44,000 to 41,000 years BP
Possible place of originSouth Asia, or Southeast Asia
AncestorPF5850 within K2b
DescendantsP-M45 (P1~, formerly P1, a.k.a. QR) and others
Defining mutationsP295/PF5866/S8, 92R7_1, 92R7_2, F91/PF5862/V231

Haplogroup P also known as P-P295 or K2b2 is a Y-chromosome DNA haplogroup in human genetics, it forms a clade within Haplogroup K2b (K-P331). Its sister clade within K2b is K2b1 (haplogroup MS).

It was proposed to redefine the root of Haplogroup P through the novel Single-nucleotide polymorphism PF5850, yet this is so far not reflected in the International Society of Genetic Genealogy Y-DNA Haplogroup Tree nor in scientific publications.

Basal PF5850* is found in Southeast Asia. Basal P-P295* is found among South and Southeast Asians as well as Oceanians, P-FT292000 (P1b, formerly P3) with unknown distribution, and P-M45* (P1~*) commonly found among Siberians and Central Asians. P-M45 is the parent node of Haplogroup Q (Q-M242) and Haplogroup R (R-M207).

The major subclades of Haplogroups P-M45, Q and R now include most males among Europeans, Native Americans, South Asians, North Africans, and Central Asians.
