摘要
目的了解贵州土家族、家人和白族人耳垂的群体遗传学特征。方法对1 212名双亲均为同一民族的贵州土家族、家人和白族人进行耳垂形态学活体观察,并根据Hardy-Weinberg定律计算耳垂的出现率和基因频率。结果贵州土家族、家人和白族人有耳垂的出现率分别为47.97%、76.21%、67.98%,显性基因频率分别为0.2787、0.5121、0.4341,隐性基因频率分别为0.7213、0.4879、0.5659。结论耳垂的遗传性状具有特异性,不同民族人群的耳垂遗传性状各不相同,存在民族、性别和地域差异。
Objective To understand the population genetics of earlobes of Tujia, Gejia and Bai populations in Guizhou province. Methods A somatological survey on 1 212 Tujia,Gejia ang Bai populations,The gene frequencies of earlobes were calculation out according to the Hardy-Weinberg law. Results Incidence of earlobes were 47. 97%, 76. 21% ,67.98%. The frequency of dominant gene of earlobes were 0. 2787,0. 5121,0. 4341, and that of recessive gene were 0. 7213,0. 4879,0. 5659 of Tujia, Gejia and Bai populations. Conclusions The earlobes have specific ge- netic traits which have different ethnic groups. There are ethnic. gender and regional differences.
