舌运动类型研究——探索临高人的族源

Study on Tongue Movement Types——Exploring the Ethnicity of Lingao

调查海南省临高人546例(男278例,女268例)的卷舌、叠舌、翻舌、尖舌和三叶舌共5项舌运动类型,得出临高人各舌运动类型的出现率和基因频率,与各族群舌运动类型出现率比较,结合语言、族源等方面,分析临高人的族属问题.结果:临高人卷舌率为57.9%,叠舌率为8.2%,翻舌率为21.6%,尖舌率为66.1%,三叶舌率为2.2%.5项舌运动类型中,仅尖舌在性别间差异具有统计学意义.临高人卷舌基因频率R=0.351,r=0.649;叠舌基因频率F=0.042,f=0.958;翻舌基因频率T=0.115,t=0.885;尖舌基因频率P=0.418,P=0.582;三叶舌基因频率C=0.011,c=0.989.聚类分析结果显示,临高人舌运动类型出现率与仫佬族、广东汉族接近.临高人民族成分由汉族、黎族、傣族、壮族融合组成的可能性大.

We investigated a sample of 546 cases of Lingao （ male 278, female 268 ） on 5 tongue movement types, including tongue rolling, tongue folding, tongue twisting, pointed tongue and clover-leaf tongue to calculate tongue move-ment types occurrence rate and gene frequency, compare the occurrence rate of tongue movement types in different ethnic groups,combine language, ethnicity,etc. and analyze the ethnicity of Lingao. Results showed that,Lingao’s tongue rolling rate was 57.9%, tongue folding rate was 8.2%, tongue twisting rate was 21.6% , pointed tongue rate was 6 6 .1% , clover- leaf tongue rate was 2.2%. Among 5 tongue movement types, significant sexual difference was only found in the frequency of pointed tongue. The gene frequency of tongue rolling was /？ = 0.351 ,r = 0.649;tongue folding was F = 0 .0 4 2 r= 0.958; tongue twisting was 0. 115, t= 0 .8 8 5; pointed tongue was P = 0 .4 1 8 ,P = 0 .582; clover-leaf tongue was C = 0. 011, c = 0.989. Cluster analysis result showed that the tongue movement types occurrence rate of Lingao were close to Mulam,Han in Guangdong. The ethnic composition of Lingao is greatly possibly made up of Han, Li, Dai, Zhuang.
