單倍群P （或P-P295、K2b2）是一個Y染色體DNA單倍群。

起源與分佈[編輯]

單倍群P(K2b2)與單倍群K2b1(SM)共同源於單倍群K2b。^[5]

P*(P-P295)少量分布於阿埃塔人和安達曼人等，雖然今天東西伯利亞和中亞都有發現P*，但是P*可能起源於東南亞，然後向北邊遷移。^[1]^[6]

P*(P-P295)有兩個分支：P1 (P-M45)和 P2 (P-B253)。^[1]

P1是單倍群Q和單倍群R的祖先,目前單倍群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，單倍群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。
