单倍群P-P295
单倍群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 | 东南亚 [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 |
起源与分布
编辑单倍群P(K2b2)与单倍群K2b1(SM)共同源于单倍群K2b。P-P295有两个分支：P1 (P-M45)和 P2 (P-B253)。[5][1]
目前阿埃塔人和安达曼人等有发现P*，虽然在东西伯利亚和中亚都有发现P*，但是P可能起源于东南亚，然后向北边迁移。[1][6]
P1是单倍群Q和单倍群R的祖先,目前单倍群R主要分布在印欧人、巴斯克人、马扎尔人、巴什基尔人、乌孜别克人、柯尔克孜人、阿尔泰人等，单倍群Q主要分布于美洲原住民、楚科奇人、堪察加人、叶尼塞人、图瓦人、土库曼人等。
P2目前有分布于菲律宾。
