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.

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.
