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

The pottical type, palmar and plantar digital formulae, hand clasping, arm folding, handedness, leg folding and stride type have been investigated on a sample of 143 male and 160 female students of the Daur population of Molidawa Banner, Inner Mongolia. The results of this study are the following: 1. the frequency of the hyperextensive pottical type is 49.17%, the relative length of index over annularis 12.21%, right hand clasping 45.87%, right arm folding 49.50%, right handedness 94.39%, right leg folding 72.28% and right stride type 44.88%, 2. pottical type, hand clasping, handedness, leg folding and stride type do not show significant sex differences, 3. there are some relations between hand clasping and arm folding as well as between arm folding and stride type, 4. compared with other population groups, the Daur population shows a low frequency of right hand clasping, a moderate frequency of right arm folding and a low frequency of left handedness.  相似文献

14 population groups of Sikkim (India)--Lepchas (2), Bhutias (2), Sherpas, Tamangs, Gurungs, Mangars, Rais, Limboos/Subbas, Pradhans (Newars), Brahmans, Chhetris, Scheduled Castes--have been studied in regard of the intra- and intergroup variability of colour blindness, ear lobe attachment, mid-phalangeal hair and behavioural traits (tongue folding, hand clapsing, arm folding, leg folding, handedness). Some of these variables show a considerable distribution heterogeneity, which is discussed considering history and marriage patterns of these populations. As most of them are highly endogamous one can assume that this heterogeneity is caused by locally acting factors such as drift and/or founder effects, which could be preserved due to as good as lacking gene flow among the populations under study. Beyond that the Sikkim data are compared briefly with those reported for other Indian and Asiatic populations.  相似文献

Only a few authors examined several lateral asymmetries in families simultaneously. Seven lateralities (handedness, footedness, eyedness, earedness, hand clasping, arm folding and leg crossing) were examined in a sample of 292 biologically related parent-offspring triads and 36 sibling pairs. Analysis of the family data showed a significant association between parents and children in most lateralities. The frequency of left-sidedness increased with the number of left-sided parents. Only in the case of footedness and hand clasping there are no significant correlations. Additionally we investigated the inter-relationship between the lateralities in the parental generation. There is a relative strong relation especially among the functional asymmetries. The study analysed also the genetic association (linkage) according to McManus & Mascie-Taylor (1979) between seven different lateralized characteristics. It is shown that the lateral asymmetries correlate genetically relatively imperfectly with each other comparing the inter-relationship between the lateralities in the parental generation. This implicates a multigenetical and also multifactorial determination of laterality in human being.  相似文献

A Hungarian twin study on hand clasping, arm folding and tongue curling   总被引:1,自引:0,他引:1  
A twin study was performed in adult Hungarian monozygotic and dizygotic pairs for hand clasping, arm folding and tongue curling. Genetic background of these traits could not be confirmed, although there appears to be a positive correlation between hand clasping type and handedness.  相似文献
