Abstract: A survey on distribution of Kidd, Duffy, Kell, Xg, Rh, Diego and P blood groups was carried out in 1985 in the Yi nationality (Butao County, Sichuan Prov.), Tibetan ( Lhasa City, Tibetan Autonomous Region) and Manchu nationality (Xiuyan County, Liaoning Prov.).
The gene frequencies observed were as follow:
Yi-Jk2 0.4144, Fy2 0.9628, K 0.000; C0.7215, c 0.2785, D 1.0000, d 0.0000, E 0.2223, e 0.7777, CDe 0.7215, cDE 0.2223, cDe 0.0562.
Tibetan-Jk2 0.4447; Fy2 0.9498; K 0.0051; C 0.6946, c 0.3054, D 0.9293, d 0.0707, E 0.3201, e 0.6799, CDE 0.0931, Cde 0.5270, Cde 0.0709, cDE 0.2270, cDe 0.0820; Xg2 0.4030; Di2 0.0255; P1 0.2138.
Maiichu-Jk2 0.4262; Fy2 0.9405; C0.6056, c 0.3944, D 0.9020, d 0.0980, E 0.3600, e 0.6400, CDE 0.0666, CDe 0.4406, Cde 0.0976, cDE 0.2934, cDe 0.1018; Xg2 0.3887; Di2 0.0168; P1 0.1577.
