單倍群 O（O-M175） 是一個人類 Y 染色體 DNA 單倍型類群，與單倍群 N 共同源於單倍群 NO，主要分布於東亞、東南亞、太平洋島嶼、馬達加斯加、中亞、南亞等。



起源

單倍群 O 首次出現於距今約 3-4 萬年前 



分布

單倍群 O 分佈於東亞、東南亞、密克羅尼西亞群島、美拉尼西亞、玻里尼西亞、馬達加斯加、中亞、南亞等。由單倍群 O 分出的兩個下游單倍群分別為 O-F265 與 O-M122。

O-F265 單倍群的名稱為 O1，分 O1a (O-M119) 與 O1b (O-M268)，下游支系如 O1a-M119 常見於中國東南部、馬來群島東北部、美拉尼西亞東部島嶼、非洲東南部的馬達加斯加島等地，O1b1a1-PK4 常見於中國西南部、中南半島、馬來群島西南部等地，O1b1a2-Page59 主要分佈於中國東部沿海省份等地，O1b2-M176 常見於朝鮮半島、日本列島等地。

O-M122 單倍群的名稱為 O2，分 O2a (O-M324) 與 O2b (O-F742)，下游支系如 O2a2a-M188 主要分佈在中國南方等地，O2a1b-IMS-JST002611、O2a2b1a1-M117、O2a2b1a2-F114 是漢族的主要單倍群，也常見於蒙古族科爾沁部、滿族、朝鮮族等中，M117 也常見於藏緬語族各族，F114 還在哈薩克族乃蠻部中高頻分布，O2a2b2-AM01822 主要分佈在中國華北偏東部、玻里尼西亞等地，O2b-F742 主要分佈於中國東部沿海省份等地。
