单倍群P-P295

單倍群P （或P-P295、K2b2）是一个Y染色体DNA单倍群 。

单倍群P (K2b2)
起源时间约3.5万 距今[1]
共祖年代{{{TMRCA}}}
起源地東南亞 [2][3]
上游单倍群K2b [4]
下游单倍群单倍群P1 (P-M45) 以及 单倍群P2 (P-B253).
P1是单倍群Q和单倍群R的祖先。
对应突变P295/PF5866/S8, 92R7_1, 92R7_2, F91/PF5862/V231

起源與分佈

單倍群P(K2b2)與單倍群K2b1(SM)共同源於單倍群K2b。P-P295有两个分支：P1 (P-M45)和 P2 (P-B253)。[5][1]

目前阿埃塔人和安達曼人等有發現P*，虽然在东西伯利亚和中亚都有發現P*，但是P可能起源于东南亚，然後向北边迁移。[1][6]

P1是单倍群Q和单倍群R的祖先,目前单倍群R主要分佈在印歐人、巴斯克人、馬扎爾人、巴什基爾人、烏孜別克人、柯爾克孜人、阿爾泰人等，单倍群Q主要分佈於美洲原住民、楚科奇人、堪察加人、葉尼塞人、圖瓦人、土庫曼人等。

P2目前有分佈於菲律賓。
