摘要: 目的 了解贵州亻革家人和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412名亻革家人(男性217人,女性195人)和342名仫佬族(男性156人,女性186人)的拇指类型、中指毛、环食指长和小指弯曲等4项遗传特征进行调查。结果 贵州亻革家人拇指类型、中指毛、环食指长和小指弯曲的显性性状出现率分别为47.6%、53.2%、17.2%和45.4%,仫佬族分别为7.6%、27.8%、5.3%和95.0%,两民族同一遗传特征出现率间差异均具有极显著性(P<0.01)。亻革家人环食指长与小指弯曲,仫佬族拇指类型与小指弯曲之间存在明显的遗传关联性(P<0.01)。结论 贵州亻革家人、仫佬族拇指类型、中指毛、环食指长和小指弯曲等4项遗传特征分布存在民族差异,且彼此相关性极小。

Abstract: Objective To understand the features of some genetic characters of Gejia groups and Mulan nationality in Guizhou. Methods A morphological survey on 342 random people of the Mulan (male156, female 186) and 412 Gejia (male217, female 195) living in Majiang and Huangping county in Guizhou respectively were carried out. Meanwhile, the frequencies of four genetic characters were calculated, and its’ correlations were analyzed. Results The frequencies of dominant characters of thumb style, hair of middle finger, style of fore and ring finger, curl of little finger in Mulan were 7.6%, 27.8%, 5.3%, and 95.0% respectively. Those of Gejia were 47.6%, 53.2%, 17.2%, 45.4% respectively. The style of fore and ring fingers was significantly correlated with the curl of little finger in Gejia, and the thumb style was significantly correlated with the curl of little finger in Mulan(P<0.01). Conclusions Four genetic characters have ethnic differences between the Mulan and Gejia in Guizhou, and these indices show a little correction.
