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 nasal tip morphological characteristics of Xibe and Han middle school students aged 11-16 in Xixi Middle School, Huangjia Township, Shenbei New District, Shenyang City, China. Methods Wu Rukang and other “anthropometric methods” and Shao Xiangqing “body measurement manual” method to observe the subjects nose tip morphology. Results The Xiphium Dominant Gene frequency of Liaoning X = 0.0617, the frequency of azygotic recessive gene a = 0.9383, the A nosignificant gene frequency of Liaoning Han A = 0.1008, the apex of the nose a = 0.8992. Conclusion There was no significant difference in gene frequency distribution between male and female in Liaoning Xibe population (P> 0.05). There was no significant difference in genotype distribution between male and female in Liaoning Han population (P> 0.05) (P <0.05). Compared with other nationalities in China, the Xiphoid morphology gene frequency in Liaoning Xibe is moderate.
