摘要： 调查了宁夏回、汉族拇指类型、环食指长、扣手、交叉臂及惯用手等 5项人类遗传学经典指标 ,结果显示 :(1) 2民族间环食指长百分率有极显著的差异 (P< 0. 0 5 )。(2 )拇指类型、扣手、交叉臂及惯用手百分率无性别间差异 ,男性环指长百分率高于女性 ,差异显著 (P <0.05) 。( 3) 惯用手与扣手、交叉臂之间存在明显的相互关系, 交叉臂与扣手之间无关。

Abstract: It was investigated 5 general indexes of anthropological genetics including pollical type, palmar digital formula, hand clasping, arm folding and handedness in Hui and Han Nationalities of Ningxia. The results showed as follows: (1) There were extremely significant difference in the frequency of palmar digital formula in 2 nationalities (P <0.01), but those of arm folding, hand clasping, pollical type and handedness showed no significant differencies. (2) There were no significant sex difference in the frequency of pollical type, hand clasping, arm folding and handedness. The frequency of long type of ring finger in male is higher than that in female, and the difference is much clear (P <0.01). (3) There were obvious correlation between handedness and hand clasping 、handed- ness and arm folding, but no relation between arm folding and hand clasping.
