摘要 目的:调查西安地区强奸犯人群13个STR基因座多态性分布,为建立法医DNA数据库提供资料。方法:采用多色荧光标记引物,复合扩增13个STR基因座,扩增产物进行Genescan扫描,Genotyper分型。建立该人群13个STR基因座的基因和基因型频率数据。结果:共检测出106种等位基因,其频率分布在0.0083~0.5500;235种基因型,其频率分布在0.0167~0.5000。平均杂合度为0.7648。累积个体识别力为0.9999999。非父排除率为0.9999999。多态信息总量分布在0.5544-0.8679。累积偶合率为10-14。结论:该13个STR基因座可以很好应用于法医DNA数据库的构建。
