摘　　要：调查了云南省通海县208例(男105例,女103例)蒙古族的拇指类型、环食指长、指甲形状、足趾长4项人类群体遗传学特征.结果显示:(1)云南蒙古族直型拇指率为79.81%,环指长率为79.33%,指甲形状长型率为40.39%,方型率为43.27%,扁型率为16.35%,足趾类型拇趾长率为60.58%.(2)云南蒙古族环食指长、指甲形状出现率性别间存在极显著性差异,拇指类型-环食指长相关显著,其他两两特征间均未表现出明显相关关系.(3)云南蒙古族与内蒙古地区蒙古族人群相比,多存在极显著差异.A sample of 208middle school students（105males,103females）of Mongolian in Tonghai County of Yunnan was investigated on four genetic characters.The results were as follows：（1）The frequencies of the straight thumb were 79.81%and the ring-finger-longer were 79.33%.The frequencies of the long-shaped fingernail were 40.39%,the square-shaped were 43.27%and the squat-shaped were 16.35%.The frequencies of the big toes were 60.58%.（2）There were significant sexual differences in the frequencies of fingernail type and palmar digital formu-la.The thumb type was significantly correlated with the palmar digital formula.（3）Compared with the Mongolian groups in Inner Mongolia area,which of Yunnan had existed significant differences on four genetic characters.
