摘要: 从1998~2001年调查了内蒙古自治区鄂尔多斯市、锡林郭勒盟、巴彦淖尔盟的蒙古族、汉族6个群体的拇指类型、环食指长、指甲类型、足趾长等4项人类群体遗传学指标,共获有效资料2760例。研究表明:(1)6个群体的直型拇指出现率均在60%以上,且均无性别间明显差异;(2)6个群体环指长率均远高于食指长率,有4个群体存在性别间显著差异;(3)各群体均表现出长型指甲最多、方型次之、扁型最少;(4)6个群体均多为拇趾长型,且各群体均无性别间显著差异;(5)4项指标之间无明显相关关系。
Abstract:From 1998 to 2001,a sample of 2760 Mongol and Han individuals was investigated in 3 areas (Eerduosi city,Xilinguole and Bayannaoer leagues) from Inner Mongolia.Each individual was studied on 4 genetic characters (thumb type,palmar digital formular,fingernail type and plantar digital formular).The result is as follows:(1) The frequencies of the straight thumb were over 60%,and there were no significant sexual differences in all of 6 groups.(2) The frequencies of the ring-finger-longer were much higher in 6 groups,and there were significant sexual differences in 4 groups.(3) The frequencies of the long-shaped fingernail were the highest in all groups,the squat-shaped were the lowest.(4) The big toes were longer than the second toes in most people of 6 groups,but without significant sexual differences in each groups.(5) There were no significant correlations between 4 characters.
