本文研究了吉林省延吉市大、中、小学生样本１８４６例（朝鲜族９６７人，汉族８７９人）的卷舌、折舌、扭舌和三叶舌运动。结果表明，这些运动能力没有民族差别；性别差异仅在扭舌中出现，这是由于女性的学习扭舌能力比男性强造成的。家系分析结果表明，卷舌能力为显性遗传，折舌和扭舌为隐性遗传，三叶舌的遗传方式是不规则显性遗传（外显不全），且外显率很低。 In this paper, we study the rolling, folding, twisting and trilobing tongue movements of 1846 samples (967 Korean and 879 Han) of primary, secondary and primary school students in Yanji City of Jilin Province. The results showed that there was no ethnic difference in these motor skills; gender differences only appeared in the twisted tongue, which was due to the fact that women had a stronger ability to learn to tongue-in-tongue than their male counterparts. The results of pedigree analysis showed that the ability of curling tongue was dominant, the tongue and tongue were recessive, the tongue of cloverleague was irregular dominant (incomplete) and the penetrance was very low.
