摘　　要：作者于１９９６年在内蒙古调查了汉、回、蒙古族５项人类遗传学经典指标（拇指类型、环食指长、扣手、交叉臂、惯用手）。研究结果显示：（１）３个民族间拇指类型、扣手出现率存在显著性差异，交叉臂、惯用手出现率则无显著性差异，环食指长出现率蒙—汉、蒙—回间存在显著性差异；（２）拇指类型、扣手、惯用手出现率无性别间差异，环食指长出现率男女间存在显著性差异；（３）惯用手与扣手、惯用手与交叉臂间存在明显的相互关系，交叉臂与扣手之间则无关；（４）与国外人群比较，３个民族环指长出现率高，交叉臂Ｒ型出现率较高，扣手Ｒ型出现率较低，惯用手Ｌ型出现率高于印度的一些群体。Authors investigated 5 general indexes of anthrotogical genetics including pollical type,palmar digital formula, hand clasping,arm folding and handedness in Han,Hui and Mongol nationalities in 1996 The results showed as follows:(1) There were significant differences in the frequency of pollical type and hand clasping in 3 nationalities,but those of arm folding and handedness showed no significant difference and the frequencies of palmar digital formula between the Mongol and the Hui revealed significant difference (2) There were no significant sexual difference in the frequency of pollical type,hand clasping and handedness while the long type (R)of ring finger revealed significant sexual difference (3) There were obvious corelations between handedness and hand clasping,handedness and arm folding but no relation between arm folding and hand clasping (4) In comparison with foreign ethnic groups,the 3 nationalities showed higher frequences of long type(R)of ring finger and right-arm folding but the frequence right-hand clasping revealed slightly lower The findings showed higher frequence of Left-Handedness than that of Indian population
