摘　　要：目的:探讨辽宁锡伯族扣手不对称行为特征及基因频率。方法:采用人体测量方法,调查辽宁沈阳某中学15~18岁锡伯族学生234名(男生120名,女生114名)扣手不对称行为特征,比较男女扣手不对称行为特征出现率差异,扣手不对称行为特征与文献报道的其他14个民族群体的亲疏性关系分析,采用组间链接平方Euclidean距离法进行聚类分析。结果:扣手不对称行为特征中右型扣手为显性性状。辽宁锡伯族扣手不对称行为特征显性基因频率为0.2839,隐性基因频率为0.7161,右型扣手出现率(48.72%)低于左型扣手出现率(51.28%),但男女生扣手不对称行为特征的基因频率及基因型频率的观察值比较差异无统计学意义。辽宁锡伯族右型扣手出现率与贵州革家人、仫佬族、贵州彝族、云南摩梭人比较差异有统计学意义(P<0.05)。聚类分析结果显示,与国内14个民族群体相比,辽宁锡伯族右型扣手不对称行为特征与羌族最为接近。结论:辽宁锡伯族扣手不对称行为特征右型出现率及基因频率均处于较低水平。Objective:To explore the gene frequency of hand clasping in Xibo nationality in Liaoning.Methods:Using anthropometric methods,the characteristics of asymmetrical clasping behavior of 234 Xibo students aged 15 to 18 year-old(120 males and114 females)in Liaoning were investigated.The incidence of asymmetrical hand clasping behavior was compared between male and female students.The relationship between the asymmetrical hand clasping behavior and the other 14 ethnic groups reported in the literature was analyzed,the clustering analysis was carried out using the Euclidean distance method of link square between groups.Results:The dominant gene frequency of the asymmetry behavior was 0.2839,and the recessive gene frequency was 0.7161.The incidence of right-type clasps was 48.72%,which was lower than that of left-type clasps(51.28%).There was no significant difference between male and female students in the results of gene frequenty and genotype frequenty.The incidence of asymmetrical right-hand clasping of the Xibo nationality was significantly different from that of the Ge family,Mulao,Yi nationality and Mosuo(P<0.05).Clustering analysis showed that compared with 14 ethnic groups in China,the characteristics of asymmetrical right-hand clasping behavior of the Xibo nationality in Liaoning were closest to that of Qiang nationality.Conclusion:The incidence of asymmetrical right-hand clasping behavior and gene frequency of Xibo nationality in Liaoning are at low levels.
