摘　　要：目的:了解贵州布依族、苗族、水族和白裤瑶眼部遗传性状基因频率分布特征。方法:采用群体遗传学公认的方法,对贵州布依族、苗族、水族和白裤瑶眼色、眼裂开度和眼裂方向3对遗传性状进行调查,并计算出各遗传性状的基因频率。被调查者年龄18～55岁,三代均为同一民族。结果:贵州布依族、苗族、水族和白裤瑶眼色的显性基因频率分别为0.0376、0.0493、0.0488和0.0110,眼裂开度的显性基因频率分别为0.6763、0.7048、0.8139和0.6769,眼裂方向的显性基因频率分别为0.0816、0.1441、0.1969和0.0575。结论:眼裂方向性状的民族间差异较大,眼色、眼裂开度则较小。Objective： To study the distribution of gene frequencies of eye genetic characters in Buyi, Miao, Shui and Baiku Yao nationalities in Guizhou province. Methods： A survey on Somatoscopy of three genetic characters （ eye colour, opening height of eyeslits and direction of eyeslits） of Buyi, Miao, Shui and Baiku Yao nationalities living in Guizhou was carried out, and their gene frequencies were calculated out, according to the investigative method of human population genetics. The sample of adults aged between 18 to 55 years old, and their parents, grandparents and maternal grandparents were same nationality. Resttlts： The frequency of dominant gene of the Eye colour in Buyi, Miao, Shui and Baiku Yao nationalities were 0. 037 6, 0. 049 3, 0. 048 8 and 0. 011 0 respectively; those of the opening height of eyeslits were 0. 676 3, 0. 704 8, 0. 813 9 and 0. 676 9 respectively; those of the direction of eyeslits were 0. 081 6, 0. 144 1, 0. 196 9 and 0. 057 5 respectively. Conclusion： The difference of direction of eyeslits among nationalities was significant, followed by eye colour and opening height of eyeslits
