湖南苗族、侗族5项人类群体遗传学特征的调查

对湖南苗族、侗族共648例的5项人类群体遗传学特征(利眼、足趾长、起步类型、耳耵聍、指甲型)进行了调查。结果显示:1)两个民族的多数人属于右利眼、拇趾长于二趾、左起步、干型耵聍和长形指甲;2)两个民族的左利眼出现率和拇趾长于二趾的出现率高于国内多数人群;3)足趾长出现率存在明显的民族间差异;苗族利眼和方形指甲出现率均表现出明显的民族内性别差异;4)5项特征间的相关关系不明显。

An Investigation on Five Human Population Genetic Characters of the Miao and Dong Nationalities in Hunan Province, China

Five genetic traits(eye preference,plantar digital formulae,stride type,earwax and finger nail type) of a sample of 648 people from the Miao and Dong nationalities in Hunan province was studied.The results of this study are given below.1) In both nationalities,most people had the following characteristics:right eye preference,1>2 of plantar digital formulae,left stride type,dry earwax and long finger nail form.2) The frequencies of left eye preference and 1>2 of plantar digital formulae was greater than that of most other nationalities in China.3) There were significant differences for plantar digital formulae between the Miao and Dong groups,and there was a significant sexual difference for eye preference and square finger nail form in the Miao.4) There were no significant correlations between any of the five genetic traits.
