摘要
调查了我国克木人285例(男为141例,女为144例)的鼻梁侧面观、鼻孔形状、下颏类型、拇指类型、环食指长、卷舌、扣手共7项人类群体遗传学经典指标.研究结果显示:(1)凸型鼻梁率、过伸型拇指率存在性别间差异.突型下颏率、鼻孔形状、拇指类型、扣手右型率、卷舌率不存在性别间差异.(2)与我国其他族群相比,克木人突型鼻梁率较低、宽鼻孔率高、突型下颏率低、拇指过伸型率低、食指长率较高、扣手右型率高、卷舌率低.这表明我国克木人有较独特的遗传特征.(3)我国克木人7项遗传学指标之间彼此相关不明显.
A sample of 285 Khmu（141 males,144 females） was investigated on 7 human population genetic characters,including nasal profile,nostril type,chin type,pollical type,palmar digital fomula,tongue rolling and hand clasping.The results were as follows：（1） No significant sexual difference were found in the 7 human population genetic characters except nasal profile and pollical type.（2） Comparing with other ethnic groups,Khmu had a higher frequency of wide nostril,but other characters had lower frequency.（3） Correlations were quite little among 7 human population genetic characters.
