摘 要：调查了海南居住较为集中的黎、苗、汉族(共3 207人)扣手、交叉臂、惯用手等人类左右不对称行为特征。结果显示：(1)扣手、交手臂、惯用手三型3个民族的出现率均为R>L型，惯用手的R型出现率远较其他两型高，呈高度显著性差异，(P<0.01)。(2)扣手、交叉臂出现率与性别无关。(3)惯用手R型出现率苗族女性明显高于男性，差异显著(P<0.05)。三民族总和出现率为89.06％，是国内外属最低的。(4)扣手与交叉臂、扣手与惯用手，交叉臂与惯用手之间均具有相当明显的相关性。

Abstract：It was investigated that three types of many general indexes of anthrotogical genetics,which include handclasping、armfolding and handedness,just among Li,Miao and Han nationalities in Hainan.There were 3207 people investigated in total.The results showed as follows:(1)The frequency of handclasping,armfolding and handedness is far higher than others(P<0.01).(2) It was proved that there was no signilicant difference between male and female in the frequency of either handclasping or armfloding.(3)It was obvious that the frequency of type R handedness in female of Miao nationality was higher than in male.And the difference was much clear(P<0.05).The total frequency of handedness was about 89.06 percent,which was the lowest rate as far as we known.(4)There was correlation among handedness and handclasping,handedness and armfolding andhandclasping and armfolding respectively.
Key words：handclasping;armfolding;handedness
目前国内有关扣手、交叉臂以及惯用手的研究较少见〔1〕，我们对居住在海南岛较为集中的黎、苗、汉族进行了上述三项指标的调查，分析其分布频率，为中国人的群体遗传学研究提供资料。
1 调查对象和方法
本文分别调查了黎族1 197人，苗族717人，汉族1 293人，共3 207人。其中，黎、苗族选择通什、保亭、陵水、乐东、琼中、昌江等县市的19个自然村的村民及学生，汉族选择人口较为集中的海口、三亚、文昌三县市的部分居民和学生，年龄均为10岁以上。调查采用小区域尽可能全部取样的方式，均先由观察对象学会扣手、交叉臂的[1] [2] 下一页
