摘要: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。 关键词:卷舌;叠舌;翻舌;尖舌;三叶舌 中图分类号:Q39 文献标识码:A 文章编号:0253-9772(1999)05-0020-22

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. Key words: Rolling tongue;Folding tongue;Twisting tongue;Pointed tongue;Clover-leaf tongue
舌的特殊运动类型是由遗传因素决定的。Sturtevant(1940)〔1〕最先研究了卷舌,认为卷舌是受一对等位基因控制的显性遗传性状。Hsu(1948)〔2〕确认叠舌为隐性性状。Gahres(1952)〔3〕提出翻舌是不依赖其他舌运动能力的独立性状。Whitney(1950)〔4〕认为三叶舌是一种外显率很低的显性能性状。至于各种舌运动类型的基因间关系,Liu(1949)〔5〕认为卷舌与叠舌基因间有互作关系,郑连斌等(1997)〔6〕的研究结果也支持这一观点,而Lee(1955)〔7〕和Hirschhorn(1974)〔8〕则认为这两个基因间不存在基因互作关系。 达斡尔族最初分布于贝加尔湖以东、黑龙江以北地区,目前主要分布于我国东北、新疆等地。〔9〕本文的调查目的在[1] [2] [3] 下一页 上一个医学论文: 中国南方汉族群体MPSI型Kpn I酶切位点的遗传多态性 下一个医学论文: 乌鲁木齐维吾尔人两种物质味盲基因频率
