汉族湘语方言族群舌运动类型的遗传学研究

为探究湖南汉族5项舌运动类型的特征,对湖南双峰县507例(男269,女238)汉族人群的卷舌、叠舌、翻舌、尖舌、三叶舌共5项性状进行了调查.结果显示:(1)湘语汉族卷舌率为64.30％,叠舌率为10.26％,翻舌率为23.08％,尖舌率为64.50％,三叶舌率为4.54％.(2)在我国族群中,湘语汉族叠舌率偏高,翻舌率、卷舌率、尖舌率中等,三叶舌率偏低.(3)除卷舌和尖舌外,其他3项舌运动类型的出现率与性别间均无显著性差异.(4)翻舌与卷舌、翻舌与叠舌存在基因互作关系；尖舌与卷舌、尖舌与翻舌存在基因互作关系.

Genetic studies of tongue moving types in Xiang dialects population

To investigate the character of five tongue moving types of Han nationality in Hunan province,A sample of 507 student s of Han(268 males,239 females) was investigated on 5 tongue moving types,including tongue rolling,tongue folding,tongue twisting,pointed tongue and clover-leaf tongue.The results were as follows:(1) The frequencies of tongue rolling,tongue folding,tongue twisting,pointed tongue and clover-leaf tongue were 64.30%,10.26%,23.08%,64.50 % and 4.54 % respectively.(2) Comparing with other nationalities,Loudi Han had a higher frequency of tongue folding The frequencies of tongue twisting,tongue rolling,pointed tongue were middle.,clover-leaf’s frequencies is lower.(3) No significant sexual difference was found in the frequencies of tongue moving types except tongue rolling and pointed tongue.(4) The genes of tongue rolling and tongue folding had interactive relations with the gene of tongue twisting.The genes of tongue twisting and tongue rolling had interactive relations with the gene of pointed tongue.
