外婆在亲子鉴定中的作用

The Effect of Grandmother on Paternity Testing

在母亲DNA信息缺失情况下 ,用外婆代替母亲在亲子鉴定中的地位 根据Essen -M ller计算理论 ,得到在假设父 -子 -外婆三联体的亲权指数的计算公式 随机模拟结果表明 ,比起父 -子单亲鉴定 ,外婆的DNA信息能有效增加亲子鉴定中作正确判断的把握 ,降低误判风险 适当增加检测位点数 ,外婆就可替代母亲在亲子鉴定中的作用 此外 ,在亲子鉴定中 ,外公、舅舅。

When the mothers genotype is missing, we can use grandmothers information instead in paternity testing. Applying the calculation theory of Essen-Mller, the formula of paternity index for the alleged father-child-grandmother triplet were provided. The simulation study shows that, compared to alleged father-child paternity testing, the grandmothers DNA information can greatly increase the efficiency of parternity testing and decrease the risk of misjudgement. With more loci tested, the grandmother can be used as a appropriate subsititute for the mother. In addition,grandfather, aunt, and uncle play the same role on paternity testing as grandmother.
