内蒙古三个民族舌运动类型的遗传学研究

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.

Genetic Study on Tongue Moving Types in Three Nationalities of Inner Mongolia

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.
