调查了内蒙古达斡尔族舌运动类型(卷舌、叠舌、翻舌、尖舌、三叶舌),共480例(男239例,女241例)。研究结果显示:(1) 卷舌、叠舌、翻舌、尖舌、三叶舌出现率分别为80.42%、4.58%、31.25%、81.88%、31.46%;(2) 卷舌、三叶舌出现率存在性别间明显差异;(3) 卷舌基因与翻舌、三叶舌基因间存在互作关系,翻舌基因与叠舌、尖舌、三叶舌基因间存在互作关系;(4) 卷舌、叠舌、翻舌、三叶舌的出现率存在民族间或种族间差异。
Abstact: A sample of 480 cases (239 males, 241 females) of Daur nationality in Inner Mongolia was investigated on 5 tongue moving types including rolling, folding, twisting, pointed and clover-leaf tongues. The results revealed as follows: The freqencies of rolling, folding, twisting, pointed and clover-leaf tongues were 80.42%, 4.58%, 31.25%, 81.88%, and 31.46%, respectively. Significant sexual difference was showed in the frequency of rolling and clover-leaf tongues. Furthermore, some genetic interaction occured between twisting tongue and the other 4 tongue moving types, rolling tongue and clover-leaf tongue, respectively. The 5 tongue moving types but pointed tongue showed national or racial difference. 相似文献

采用Penrose先证者同胞法和分离分析方法对72个家系资料的分析表明:卷舌、尖舌均为常染色体单基因显性遗传,阳性为显性性状;翻舌为常染色体单基因隐性遗传,阳性为隐性性状。虽然环境因素对这类特征的表现也有一定的影响,但遗传因素仍起主要作用。
Abstract:The data of 72 families were analyzed by the method of proband′s sib and the method of segregation analysis.The results showed that the hereditary mode of rolling tongue or pointed tongue is the dominant heredity of single gene of autosome,and the positive type of them is the dominant character;Twisting tongue is the recessive heredity of single gene of autosome,while the positive type is the recessive character.Present study suggested,although environmental might affect these characters,hereditary factors seemed to be dominant. 相似文献

内蒙古5个民族12对性状的基因频率 总被引:32,自引:2,他引:30
报道了内蒙古地区鄂温克、鄂伦春、达斡尔、蒙古族和汉族12对遗传性状的基因频率,并进行民族间基因频率的比较。结果显示:内眦褶性状的民族间差异较大,叠舌性状次之,利手和鼻梁侧面观性状的民族间差异较小。
Abstract:The gene frequency of 12 characters was reported in Ewenki,Oroqen,Daur,Mongol and Han nationalities in Inner Mongolia,and compared among these nationalities.The result indicated that the difference of Mongoloid fold among nationalities was significant,followed by the Folding tongue,while the difference of Handedness and Nasal profile was relatively insignificant. 相似文献

应用随机群体抽样方法对广东梅州地区203例客家人(其中男68例,女135例)的卷舌、叠舌、翻舌、尖舌、三叶舌5项体质人类学指标进行调查,与国内外族群资料进行比较,分析了5项指标间的相互关系。结果显示,1)广东客家人卷舌率为63.05%,叠舌率为6.90%,翻舌率为34.48%,尖舌率为67.98%,三叶舌率为3.45%。与国内族群比较,广东客家人卷舌率较低,叠舌率中等,翻舌率较高,尖舌率较低,三叶舌率低。2)广东客家人舌运动类型出现率与四川邛崃汉族最为接近,具有南方族群的特征。3)广东客家人只有卷舌-翻舌间存在着相关。卷舌基因与叠舌基因是相互独立的。 相似文献

4 anthroposcopic markers in the Northern Greece population: hand folding, arm folding, tongue rolling and tongue folding 总被引:1,自引:0,他引:1
A Pentzos-Daponte 《Anthropologischer Anzeiger; Bericht über die biologisch-anthropologische Literatur》1986,44(1):55-60
Four anthroposcopic traits, namely hand clasping, arm folding, tongue rolling and tongue curling have been studied in a total of 7763 individuals from Thessaloniki and its surroundings, representing a sample of the population of Northern Greece. The statistical analysis of the data indicates significant sex differences only concerning tongue rolling. The frequencies obtained for the four traits under study are compared with data from the literature. 相似文献
