单倍群O-M175

单倍群O首次出现于距今约3万年前[1][2]，出现地为东南亚[3][4][5][6]或东亚[7]，是单倍群NO-M214的两个下游单倍群之一（另一下游单倍群则是主要分布于欧亚大陆北部的单倍群N）。

單倍群O分佈於东亞、东南亞、波利尼西亞、馬達加斯加、中亞、南亞等。由单倍群O分出的三个下游单倍群分别为O-MSY2.2、O-M268与O-M122。其中，O-MSY2.2主要分布中国东南沿海地区、壯侗族群、南岛族群等。O-M268的主要下游支系如O-PK4，常见于中国南部汉族和少数民族及中南半岛等地，O-M176常见于朝鲜半岛、日本、中國長江流域等地，O-PAGE59相对较少常见于中国环渤海一带以及东亚周边国家亦有少量分布。而O-M122的主要下游单倍群包括O2a1b-IMS-JST002611、O2a2b1-M134（主要包括下游的O2a2b1a-M117、O2a2b1a2a-F444等支系）、O2a2a1a2-M7等，其中汉族主要由IMS-JST002611、F444、M117三个支系组成，三者比例相仿。此外，M117也常见于藏缅语族，F444还在哈萨克族乃蛮部中高频分布。而M7则在苗瑶语族与南亚语系中高频分布。O2a2b2-AM01822是波利尼西亚人的主要单倍群。
