贵州汉族7种不对称行为特征的研究

目的：了解贵州汉族不对称行为特征的分布特点,为人类群体遗传学研究积累资料。方法：采用遗传学界公认的方法对684名贵州汉族利眼、扣手、利手、利足、叠臂、叠腿和起步类型7种不对称行为特征进行活体观察,并对其关系进行相关分析。结果：贵州汉族利眼、扣手、利手、利足、叠臂、叠腿和起步类型的右型出现率分别为60.1%、82.7%、90.2%、74.4%、64.8%、71.2%、57.46%;除利眼和起步类型外其他5种特征间出现率男女间差异无显著性;起步类型与利眼和叠臂关系不明显,其他特征间具有相关性（P〈0.05或P〈0.01）,右—右组合特征类型出现比例最高。结论：贵州汉族7种不对称行为特征均以右型为主,特征出现率男女间差异多不显著,特征间多具相关性,同侧组合特征类型为其亲和特征。

Study on 7 behavioral traits of lateral functional dominance in Han nationality of Guizhou province

Objective: To understand distributive characteristics of behavioral traits of lateral functional dominance in Han nationality of Guizhou province,in order to accumulating a wealth of data for the study of human popunation genetics.Methods: Samples of 684 cases from 18-24 years old(186 males,498 females) was investigated on 7 behavioral traits of lateral functional dominance(eye preference,hand clasping,handedness,foot preference,arm folding,leg folding and stride type) in Han nationality of Guizhou province...
