作者于1996年在内蒙古调查了汉、回、蒙古族5项人类遗传学经典指标(拇指类型、环食指长、扣手、交叉臂、惯用手)。研究结果显示:(1)3个民族间拇指类型、扣手出现率存在显著性差异,交叉臂、惯用手出现率则无显著性差异,环食指长出现率蒙-汉、蒙-回间存在显著性差异;(2)拇指类型、扣手、惯用手出现率无性别间差异,环食指长出现率男女间存在显著性差异;(3)惯用手与扣手、惯用手与交叉臂间存在明显的相互关系,交叉臂与扣手之间则无关;(4)与国外人群比较,3个民族环指长出现率高,交叉臂R型出现率较高,扣手R型出现率较低,惯用手L型出现率高于印度的一些群体。 Abstract:Authors in vestigated 5 general indexes of anthrotogical genetics including pollical type,palmar digital formula,hand clasping,arm folding and handedness in Han,Hui and Mongol nationalities in 1996.The results showed as follows:(1)There were significant differences in the frequency of pollical type and hand clasping in 3 nationalities,but those of arm folding and handedness showed nosignificant difference and the frequencies of palmar digital formula between the Mongol and the Hui revealed significant difference.(2)There were no significant sexual difference in the frequency of pollical type,hand clasping and handedness while the long type (R) of ring finger revealed significant sexual difference.(3)There were obvious correlations between handedness and hand clasping,handedness and arm folding but no relation between arm folding and hand clasping.(4)In comparison with foreign ethnic groups,the 3 nationalities showed higher frequencies of long type (R) of ring finger and right-arm folding but the frequence right-hand clasping revealed slightly lower.The findings showed higher frequence of Left-Handedness than that of Indian population.  相似文献

兴安盟3个民族5种舌运动类型的研究   总被引:15,自引:0,他引:15  
人类舌头的一些特殊运动类型(如卷舌、叠舌)是人类群体遗传学的重要指标。国外学者在该方面的研究较早较多[1—3],国内学者近年也已开始涉足该领域[4—6]。本文首次对我国内蒙古兴安盟的3个民族的5种舌运动类型进行调查研究,以探讨其分布频率及特征间相关联系。1 对象与方法于1998年9月测试人员在内蒙古兴安盟乌兰浩特市当地中学进行了卷舌、叠舌、翻舌、尖舌、三叶舌的调查,共获有效资料1852例。受试者身体健康,无残疾,11—20岁,其父母均为同一民族。调查遵照学术界公认的方法进行。2 结果与讨论21 各舌运动类型的出现率比较3个民族5种…  相似文献

从词汇的视觉输入到通达它们语义的过程中是否必须中介语音信息,这是有关视觉词汇阅读理解研究领域的核心问题之一.本文报道了一位汉语脑损伤个案(YGA),他的行为模式提供了直接探讨该问题的证据.YGA存在图形命名和口语阅读困难,并在这两个任务中犯了大量语音错误,而且图形命名中还犯了大量语义错误.这表明YGA在通达语音表征的过程中出现了障碍.可是,他对词汇的视觉理解能力却保存完好.他的这种模式挑战了阅读理解的语音中介假说,进而为直接通达假说的语言普遍性提供了证据.  相似文献

鄂伦春、鄂温克、达斡尔族一侧优势功能特征研究   总被引:27,自引:4,他引:23  
陆舜华  郑连斌  李咏兰  韩在柱 《遗传》2000,22(5):287-291
报道了鄂伦春、鄂温克、达斡尔族7项一侧优势功能特征(扣手、利手、叠臂、叠腿、起步类型、优势足、优势眼)。结果显示,3个民族7项特征的左右型分布规律有较多的相似之处,绝大多数特征与性别无关。鄂温克族和达斡尔族的利手与叠腿、优势足、起步类型间均具明显关联,其腿足特征间的相关程度亦优于手臂特征。鄂伦春族则不然。 Abstract:Authors reported 7 traits of lateral functional dominance including hand clasping,handedness,arm folding,leg folding,stride type,foot preference and eye preference in Oroqen,Ewenki and Daur nationalities.The results showed as follws;(1)Among three nationalities their left and right distributive patterns of the traits had many similarities and there was no relation between most traits and sexes.(2)There were obvious corelations between handedness and leg folding,handedness and foot preference,handedness and stride type in Eweike and Daur nationalities.Compared with the traits of leg-foot with interrelation,the traits of hand-arm had little degree on correlation in Ewenki and Daur.(3)There was correlation between eye preference and hand clasping but no relation between handedness and hand clasping.  相似文献

兴安盟3个民族10对性状的基因频率   总被引:27,自引:3,他引:24  
调查了内蒙古兴安盟汉、蒙古、朝鲜族的10对遗传性状,并计算了各民族每一性状的基因频率,同时也进行了民族间基因频率的比较。比较结果显示:汉族-朝鲜族间差异较大,蒙古族-朝鲜族间次之,汉族-蒙古族间差异较小。 Abstract:Ten genetic traits were investigated in Han,Mongol and Chaoxian nationalities in Xing'an League of Inner Mongolia.The gene frequency of the traits was calculated in each nationality and compared between the nationalities.The result indicated that the difference of gene frequency between Han and Chaoxian nationalities was significant,followed by between Mongol and Chaoxian ones,whileit was relatively insignificant between Han and Mongol ones.  相似文献
