摘要/Abstract

摘要：本研究调查了湖南凤凰县苗族562例(男252例,女310例)的拇指类型、环食指长、指甲形状、足趾长、通贯纹5项人类遗传学形态特征.结果显示：（1）苗族直型拇指出现率为83.27% ，过伸型为16.73%；环指大多长于食指，环指长出现率为89.32%，食指长出现率为10.68%；扁型指甲出现率为 45.55%，非扁型指甲出现率为54.45%；拇趾长出现率为44.31%，二趾长出现率为55.69%；有通贯纹出现率(7.12%)明显低于无通贯纹出现率（92.88%）.（2）直型拇指的出现率性别间有显著差异（P<0.05），环指长出现率在性别间有极显著差异（P<0.01），指甲类型、足趾长和通贯纹无性别间显著差异（P>0.05）.（3）5项指标间均不存在相关关系.

Abstract: Five anthropological traits of total 562 people of Miao nationality(252 males,310 females ),including thumb type,palmar digital formula,nail type,planta digital formula and single flexion crease were investigated.The findings indicated that:(1)the frequency of straight thumb was 83.27%,the over stretch was 16.73%,the ring finger was mostly longer than the index finger,the frequency of longer ring finger was 89.32%,the frequency of longer index finger was 10.68%,the frequency of flat nail was 45.55%,the frequency of non-flat nail was 54.45%,the frequency of longer first toe was 44.31%,the frequency of longer second toe was 55.69%,the frequency of single flexion crease was 7.12% (much lower than that of without it);(2)the frequency of straight thumb had remarkable sex difference(P<0.05),the frequencies of longer ring finger had a remarkable sex difference（P<0.01）,the nail type,the tip of toe long and single flexion crease didn't have remarkable sex difference（P>0.05）;(3)no correlation occurred between the 5 traits.

Key words: thumb type, palmar digital formula, nail type, plantar digital formula, single flexion crease, Miao nationality
