辽宁地区汉族群体耳垂基因频率的分布

Distribution of Gene Frequencies of Ear Lobes in Han Population in Liaoning Province

目的积累人类群体遗传学研究资料。方法参考郑连斌等的研究方法检测辽宁地区汉族群体耳垂基因频率的分布。结果耳垂显性基因频率A＝0.3872（男性群体中A＝0.4490;女性群体中A＝0.3337）;耳垂隐性基因频率a＝0.6128（男性群体中a＝0.5510;女性群体中a＝0.6663）。耳垂显性基因频率在男女群体中的分布有极显著性差异。结论辽宁汉族群体有耳垂基因频率远低于无耳垂基因频率，同国内一些群体的耳垂基因频率分布相一致。

Objective To provide information of human population genetics. Methods Zheng Lianbin's method was used. Results The frequency of dominant gene (A ) wns 0. 3872 (malc population: a = 0. 5510; female population: =0.6663 ). Conclusion The frequency of dominant gene was lower than that of recessive gene in Han population in Liaoning. The dsistrbution of gene frequencies of car lobe in Han popultion in Liaoning province was consistent with that in other populations in China.
