贵州仫佬族5项人类群体遗传学特征研究

目的:了解贵州仫佬族人类群体遗传学特征的分布情况.方法:采用整群随机抽样方法,对贵州342名仫佬族(男性156,女性186)的叠舌、卷舌、前额发际、发旋、耵聍等5项群体遗传学特征进行调查.结果:贵州仫佬族叠舌、卷舌、前额发际、发旋、耵聍的显性性状出现率分别为24.6％、31.0％、38.0％、65.8％、12.9％.其中,男性分别为31.4％、25.0％、60.9％、62.2％、10.9％,女性分别为18.8％、36％、18.8％、68.8％、14.5％.结论:贵州仫佬族叠舌、卷舌、前额发际、发旋、耵聍等5项群体遗传学特征分布存在性别差异,且特征间相关性不大.

A study of five human population genetic characters of Mulan nationality in Guizhou

Objective： To investigate the distribution of genetic characters of Mulan nationality in Guizhou. Methods： Clusters were randomly selected from six Zhai in Jidong village, Majiang county in Guizhou. There were 342 Mulan people （ 156 male and 186 female） included in the study. Five genetic char- acters were investigated, including curly top of tongue, curly sides of tongue, front form of hair, hair whirl, and cerumen. Results： The rates of dominant characters of the curly top of tongue, curly sides of tongue, front form of hair, hair whirl and cerumen, were 24. 6%, 31. 0%, 38. 0%, 65. 8%, and 12. 9% , re- spectively. For male participants, these rates were 31. 4%, 25. 0%, 60. 9%, 62. 2%, and 10. 9% ; for female participants, these rates were 18. 8%, 36. 0%, 18. 8%, 68. 8%, and lg. 5%, respective- ly. Conclusions： There were differences in the five genetic characters between man and women. There seems not much correlations among these characters.
