摘　　要：目的探讨辽宁锡伯族群体眼裂方向遗传特征及其基因频率。方法采用人体测量学方法,调查了辽宁沈阳15~18岁锡伯族学生216名(男96,女120)的眼裂方向遗传特征,分析比较两性别之间的基因频率。结果眼裂方向遗传学特征中,水平对斜位为显性性状。辽宁锡伯族眼裂方向显性基因频率为A=0.3368,其中男性显性基因频率A=0.4600,女性显性基因频率A=0.2528。辽宁锡伯族眼裂方向隐性基因频率为a=0.6632,其中男性隐性基因频率a=0.5400,女性隐性基因频率a=0.7472。结论辽宁锡伯族男女性别间眼裂方向遗传特征处中等水平,但显性基因频率处于较高水平。Objective To obtain the data of the gene frequency on genetic characteristics of direction of eyeslits in Liaoning Xibe people. Methods We used the method from ＂Measurement Method of Human Body＂ and ＂Anthropometric Handbook＂ written by Rukang Wu and Xiangqing Shao. We investigated the genetic characteristics of direction of eyeslits on 216 students （15-18 years old） who lived in Hutai Middle School, New District of Xinchengzi, Shcnyang, Liaoning. We got the data of the gene frequency between the two sexes. Results According to the genetic characteristics of direction of eyeslits, the horizontal position was dominant compared with the oblique position. The dominant gene frequency of direction of eyeslits was 0. 3368 in Liaoning Xibo people. The dominant gene frequency was 0. 4600 in males, and 0. 2528 in females. The recessive gene frequency of direction of eyeslits was 0. 6632 in Liaoning Xibo people. The recessive gene frequency of dominant was 0. 5400 in males, and 0. 7472 in females. Conclusion There are significant differences in gene frequency distribution（P 〈0. 01 ）between the male and female in horizontal and oblique position in Liaoning Xibo people. Additionally, in direction of eyeslits the frequency of dominant gene is higher than other nationality with Liaoning Xibo people in China.
