Abstract: 目的调查15个STR基因座在中国鄂温克族人群中的基因频率分布.方法应用Power Plex 16System复合扩增系统,对99名鄂温克族无关个的血样DNA进行多态性研究.结果在鄂温克族人群中15个STR基因座偶合率(Pm)在0.020 5~0.173 3之间,个体识别概率(DP)在0.826 7~0.979 5之间,杂合度在0.6061~0.9091之间,三联非父排除率(PE)在0.4038~0.7690之间,多态性信息总量(PIC)在0.598 5~0.8734之间,15个STR基因座总TDP值为0.999999999999 8,所有基因座经x2检验符合Hard-Weinberg平衡.结论上述15个STR基因座在鄂温克族人群中等位基因分布较好,个体识别率高,适合法医个体识别和亲子鉴定.
