Anthropologic study on tongue moving types in GeJia people

A sample of 255 cases of GeJia people(male 133,female 122)was investigated on 5tongue moving types,including tongue rolling,tongue folding,tongue twisting,pointed tongue and clover-leaf tongue.The results as followed:(1)The Gene Frequency of tongue rolling was R=0.295,r=0.705;tongue folding was F=0.874,f= 0.126;tongues twisting was T=0.562,t=0.438;pointed tongue was P=0.259,p= 0.741;clover-leaf tongue was C=0.028,c=0.972.Signficant sexual difference was found in the frequency of rolling tongue,no significant sexual difference were found in other frequencies of 4tongue moving types.(2)In internal population,GeJia people had the low frequencies of tongue rolling,tongue foldlling,tongue pointed.The frequency of tongue,twisting lower than Dong,DuLong,Hui,Daur,and close to almost internal population.The frequency of clover-leaf tongue,had contrast statistics significance with South Asian type and North Asian type.(3)There had no contrast statistics significance between GeJia`s frequency of tongue twisting,pointed tongue,clover-leaf tongue and Miao`s.The frequency of tongue rolling,tongue folding apparent lower than local Miao`s and had contrast statistics significance.The results of cluster analysis showed that GeJia prople and Miao were similar and had the difference with other South population.(4)The tongue rolling was correlative with tongue twisting and pointed tongue.The results showed the gene of tongue rolling and tongue twisting;tongue folding and pointed tongue had interactive relations.
