【摘要】 目的调查12个YSTR基因座及其单倍型在河南汉族人群中的遗传多态性分布。方法应用PowerPlexYSystem,系统对河南汉族200名无关男性个体进行检测分析,并统计其群体遗传学参数。结果12个YSTR基因座共检出195种单倍型,其中191种单倍型出现1次,1种出现3次,3种出现2次。累积GD值:0.9988。结论12个YSTR基因座具有较强的个体识别能力,可应用于河南地区个人识别和亲权鉴定。更多还原

【Abstract】 Objective To abtain the distribution of allele frequencies and haplotype of twelve Y-chromosome STR loci of Han population in Henan and to evaluate its forensic applification. Methods DYS391、DYS389I、DYS439、DYS389II、DYS438、DYS437、DYS19、DYS392、DYS393、DYS390、DYS385 loci were applified by using PowerPlex(r)Y System,200 unrelated male individuals of han population in Henan were investigated to detmine the distribution of allele frequencies and haplotype. Results 5、5、6、7、6、5、5、8、6、5 alleles were found in the preview ten Y-STR loci,and 47 haplotypes were found in DYS385 locus. Conclusion The 12 Y-STR loci are highly polymorphic and are suitable for forensic individual identification and paternity testing in Henan Province.更多还原
