The paper deals with variation with regard to certain physical traits like AB0 blood groups, cerumen type, cross section of head hair, finger patterns and anthropometric characters in three Assamese caste populations, namely Brahmin, Kalita and Kaibarta representing three strata of the Assamese caste society. The study reveals that in respect of AB0 blood groups, cerumen type and finger patterns the Kaibartas stand apart from the Brahmin and Kalita, who are similar to one another. With regard to the other traits a different picture is observed. When the castes are arranged in hierarcheal order, the hair becomes coarser from the Brahmin to the Kaibarta through the Kalita. The metric values also can be arranged in a similar manner when certain values show a decrease from the lower to higher caste and others increase. While dealing with the nature of variation an attempt has also been made to look for the possible reasons. It appears that a host of factors like ethnic migration, inflow of genes, isolation are involved to cause variation.  相似文献

内蒙古三个民族舌运动类型的遗传学研究   总被引:28,自引:3,他引:25  
调查了内蒙古汉、蒙古、回族舌运动类型(卷舌、翻舌、叠舌、三叶舌与尖舌),共716例。研究结果显示:各种舌运动类型出现率性别间均无显著性差异;卷舌基因分别与叠、翻、尖、三叶舌基因间存在着互相作用关系,卷舌基因对叠舌基因是隐性上位基因,对翻舌、尖舌、三叶舌基因是修饰基因;内蒙古3个民族间卷、叠、尖舌出现率接近。本文首次调查并研究了尖舌性状。尖舌在过去国内外文献中未见报道。 Abstract:The tongue moving types(including tongue rolling,tongue twisting,tongue folding,clover-leaf tongue and pointed tongue)of 716 cases of Han,Mongol and Hui nationalities in Inner Mongolia were investigated.The results showed that no difference in the frequencies of various tongue moving types between male and female and that the frequencies of rolling,folding and pointed tongue were close to each other among the three nationalities of Inner Mongolia.However,some interactions between genes were revealed,that the rolling gene is a recessive epistatic gene to folding gene and a modifier gene to twisting,pointed and clover-leaf gene respectively.The research on pointed tongue in this paper has never been reported in China and abroad.  相似文献

Five characteristics (hair forms,nasal profile,nostril forms,mongoloid fold and upper eyelid fold) were respectively investigated in six nationalities,including the Buyi,Miao,Shui,Maonan,Dong,and Han nationalities in Southern Guizhou,China.The gene frequencies of five characteristics in the six nationalities were estimated and compared.The results indicated that:(1) for hair forms and nasal profile,the frequency of the dominant gene was lower than that of their recessive gene,but the opposite was true for nostril forms.(2) Among different nationalities,the difference of gene frequency of the mongoloid fold,nasal profile,hair forms and upper eyelid fold was quite significant,which was followed by that of nostril forms.  相似文献

Finger length and distal finger extent patterns in humans   总被引:10,自引:0,他引:10  
The fingers in the adult human hand differ in length and in distal extent. The literature agrees that in the clear majority of males, the distal extent of the ring finger tends to be relatively greater (using the middle finger as standard) than the index finger. However, the results for females vary considerably, with some studies reporting that females show a similar pattern to that of males, while others suggest that the prevalence of a longer index finger is relatively or absolutely more common in females. We provide a review of the literature, and a set of data for both finger length and distal fingertip extent of the finger for a contemporary cohort of young adult females and males (n = 502). Finger length measures favor the ring finger of both sexes, with smaller between-finger differences for females than for males. However, while the distal fingertip extent favors the ring finger of both hands in males, in females the left hand shows no significant differences, and the right hand shows a small index finger advantage. Thus, the sexual dimorphism in finger measures is more strongly expressed in the distal extent of fingertips than in the length of fingers. The sex differences in distal fingertip extent derive from the index finger only, with a lesser distal extent of the index finger, relative to the middle finger, in males than in females.  相似文献

海南岛黎族体质特征之研究   总被引:34,自引:18,他引:16  
黎族的体征明显属黄种人。与其他少数民族相比,在体征上与壮族、布依族、彝族和高山族较相似;与汉族相比,则与广西、广东、福建和湖南的汉族相似。因此,作者认为黎族的体征属华南类型。黎族四个组群间,在容貌上较难区分,但测量的尺寸略有不同,其中(亻考)黎与岐黎较接近,本地黎与美孚黎较接近。  相似文献

Five characteristics (hair forms, nasal profile, nostril forms, mongoloid fold and upper eyelid fold) were respectively investigated in six nationalities, including the Buyi, Miao, Shui, Maonan, Dong, and Han nationalities in Southern Guizhou, China. The gene frequencies of five characteristics in the six nationalities were estimated and compared. The results indicated that: (1) for hair forms and nasal profile, the frequency of the dominant gene was lower than that of their recessive gene, but the opposite was true for nostril forms. (2) Among different nationalities, the difference of gene frequency of the mongoloid fold, nasal profile, hair forms and upper eyelid fold was quite significant, which was followed by that of nostril forms. __________ Translated from Hereditas, 2006, 28(4): 399–402 [译自: 遗传]  相似文献
