摘要/Abstract

摘要： 本文以中国东北汉族(69例)和鄂温克、鄂伦春、达斡尔3个少数民族人群(108例)为研究对象，采用PCR产物变性聚丙烯酰胺凝胶电泳的方法分析了Y染色体特异性微卫星DYS19的等位基因分布规律。结果显示：东北汉族人群中各等位基因分布较分散A 2.9%，B 26.09%，C 26.09%，D 28.98%，E 15.94%；东北汉族和3个少数民族人群的等位基因频率有显著性差异(P<0.05)。我们还通过PCR方法调查了以上4个人群中Y染色体特异的Alu序列插入位点DYS287的多态性，在所研究4个人群中没有发现Alu序列的插入，即均为YAP-的个体。

Abstract: We analyzed the allelic distribution of Y-chromosome specific microsatellite DYS19 by PCR denatured polyacrylamide gel electrophoresis in Ha n nationality and the Daur, the Oraqen and the Ewenki ethnic groups. The result demonstrated that the allelic distribution of Han nationality was dispersed: A 2. 9% , B 26. 09% , C 26. 09% , D28. 98% , E 15. 94% . There w as significant difference of allelic distribution between the Ha n nationality and three ethnic groups( P < 0. 05). We also investigated the polymorphism o f the Y-chromosome specific Alu insert sequence DYS287 in these four groups and found no Alu sequence insert.

Key words: Y chromosome, Polymorphism, Microsatellite, Alu
