摘　　要：调查了山西汉族拇指类型、环食指长、扣手、交叉臂及惯用手等五项人类遗传学经典指标,结果显示: (1)环食指无性别间差异,扣手、拇指类型、惯用手、交叉臂等男女间存在显著性差异; (2)扣手、拇指类型、惯用手、交叉臂、环食指等性状存在地区间差异; (3)拇指类型、惯用手以及环食指三对性状的基因频率和基因型频率; (4)惯用手与扣手间存在明显的相互关系,扣手与交叉臂以及惯用手与交叉臂之间则无关.It was investigated 5general indexes of anthropological genetics including pollical type,palmar digital formula,hand clasping,arm folding and handedness in Han nationality of Shan-xi province.The results showed as follows:(1) There were significant sexual differences in the pollical type,hand clasping,arm folding and handedness,while palmar digital formula revealed no significant sexual difference;(2) There were significant district differences in the hand clasping, pollical type ,palmar digital formula ,arm folding and handedness;(3).The gene frequency and proportion of gene type for pollical type ,palmar digital formula and handedness were calculated;(4) There was obvious correlation between handedness and hand clasping,but no relation between handedness and arm folding, arm folding and arm folding.
