Haplogroup P also known as P295/PF5866/S8 and K2b2 is a Y-chromosome DNA haplogroup in human genetics. P is a branch of K2b (previously Haplogroup MPS; P331) which is a branch of Haplogroup K2 (K-M526). At present, the only ''direct'' descendant of basal P * is P1 (M45/PF5962), formerly known as P (xQ,xR). P1 is, in turn, the newly defined parent node of Q (M242) and R (M207). Basal haplogroup P *, P1, Q and R include more than one-third of the males among many modern populations in Asia, most Native Americans and most males in Europe. == Structure == (詳細はsubclades of Haplogroup P with their defining mutation, according to the 2008 ISOGG tree: *P (P295/PF5866/S8, 92R7_1, 92R7_2, F91/PF5862/V231) * * P1 (M45/PF5962) * * *Q (M242) * * *R (M207, P224, P227, P229, P232, P280, P285, L248.2, V45) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Haplogroup P (Y-DNA)」の詳細全文を読む スポンサード リンク
