内蒙古汉、回、蒙古族扣手、交叉臂及惯用手的分析

利用对数线性模型分析了郑连斌、陆舜华等1996年在内蒙古调查的汉、回、蒙古族的3项人类遗传学指标（扣手、交叉臂、惯用手）,得出与其既有相同又有不同的结论。结果显示：（1）扣手与民族、性别都无关;（2）交叉臂与民族不相关,与性别相关;（3）惯用手、民族、性别三者存在三因子效应;（4）惯用手与扣手、惯用手与交叉臂分别存在相关性,而交叉臂与扣手之间相关性不显著。     

海南黎、苗、汉族扣手、交叉臂和惯用手的研究

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 hand-clasping、arm-folding 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 hand?clasping,arm-folding 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 hand-clasping or arm-floding.(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 hand?clasping,handedness and arm-folding andhand-clasping and arm-folding respectively.
