单倍群P-P295

(重定向自单倍型类群 P (Y-DNA)

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

起源與分佈编辑

單倍群P(K2b2)與單倍群K2b1(SM)共同源於單倍群K2b。[5]

P*(P-P295)少量分布于阿埃塔人安達曼人等,虽然今天东西伯利亚中亚都有發現P*,但是P*可能起源于东南亚,然後向北边迁移。[1][6]

P*(P-P295)有两个分支:P1 (P-M45)和 P2 (P-B253)。[1]

P1是单倍群Q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中,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中。

P2目前少量分佈於菲律賓
