【摘要】 目的调查云南巍山回族人群的27个Y-STR的遗传多态性,并获得相关的基础遗传学数据,为法医学鉴定提供数据支持,促进地区Y-STR数据库的建立.方法采集云南巍山地区171名无关男性个体血液样本,应用YfilerRPlus试剂盒对所有样本进行27个Y-STR基因座PCR复合扩增,用ABI 3500型遗传分析仪对扩增产物进行毛细管电泳检测,统计相关遗传学参数.结果在171名巍山回族无关男性个体中,27个Y-STR基因座等位基因频0.005 8~0.720 7之间,基因多样性(GD)在0.431 4~0.940 8之间,共观察到169个唯一单倍型,1个单倍型观察到2次,单倍型多样性(HD)为0.999 86,系统识别能力(DC)为0.994 152.结论 27个Y-STR基因座在云南巍山回族人群中具有高度多态性,可以为法医学鉴定及Y-STR数据库的建立提供依据.更多还原

【Abstract】 Objective To investigate the genetic polymorphisms of 27 Y-STR loci in Hui population from Weishan,Yunnan Province, and obtain the genetic basic data of Hui population, to provide data support for forensic identification, and to promote the establishment of Y-STR database. Methods Blood samples of 171 unrelated male individuals were collected.DNA was amplified by using YfilerRPlus system and genotyped by ABI3500 Genetic Analyzer. The forensic parameters were calculated.Results In the 171 unrelated male individuals, the allele frequency was 0.0058~0.7207, the gene diversity(GD) was 0.4314~0.9408. 169 different haplotypes were observed once, 1 haplotype occurred twice.The haplotype diversity(HD) was0.99986 and the discriminative capacity(DC) was 0.994152.Conclusion The 27 Y-STR loci are highly polymorphic in Hui population from Weishan,Yunnan Province, and could be provided the basis for forensic identification and the establishment of Y-STR database.更多还原
