辽宁锡伯族与汉族鼻尖形态基因频率的分布

The Gene frequency of nasal tip shape in Xibo and Han nationalities in Liaoning Province

目的通过调查辽宁省沈阳市沈北新区黄家乡锡伯族中学11-16岁锡伯族与汉族中学生的鼻尖形态特征,分析了锡伯族与汉族两个群体的鼻尖形态基因频率。方法采用吴汝康等《人体测量方法》和邵象清《人体测量手册》方法,观察受试者鼻尖形态。结果辽宁锡伯族鼻尖显性基因频率A=0.0617,鼻尖隐性基因频率a=0.9383,辽宁汉族鼻尖显性基因频率A=0.1008,鼻尖隐性基因频率a=0.8992。结论辽宁锡伯族群体男女间基因频率分布无显著差异(P>0.05),辽宁汉族群体男女间基因频率分布无显著差异(P>0.05),辽宁锡伯族汉族间鼻尖形态基因频率分布有显著性差异(P<0.05)。与国内其他民族相比,辽宁锡伯族鼻尖形态基因频率处于中等水平。

Objective：To investigate the gene frequency of nasal tip shape in Xibo and Han nationalities of Liaoning province. Methods：According to the visual methods and standards in ＂Measure Methods of Human Body＂ written by Wu Ru-kang and ＂Handbook of Human Body Measurement ＂written by Shao Xiang-qing.We got Xibo nationalities and Han nationalities nasal tip shape. Results：The dominant gene frequency of nasal tip shape was 0.0617,the recessive gene frequency of nasal tip shape was 0.9383 in Liaoning Xibo nationality.The dominant gene frequency of nasal tip shape was 0.1008,the recessive gene frequency of nasal tip shape was 0.8992 in Liaoning Han nationality. Conclusion：There were significant differences in gene frequencies of nasal tip shape between Xibo and Han nationalities with no obvious difference between male and female.
