The calculation and its standard of identifying paternity in the cases of absence mother / 中国法医学杂志

To establish a calculation method of paternity probability in cases of absence of mother. Calculating the accumulated non-father exclusion probability of multiple polymorphic DNA loci was performed. The results showed that in cases of inheritance with Mendelian Law, through testing 8 or more polymorphic DNA loci, the paternity probability may reach 0. 9990 or more. In cases of paternity exclusion, exclusion 3 or more than 3 loci were required. For the purpose of identifying paternity in cases of absence of mother, more than 8 polymorphic DNA loci must be tested. The paternity probability must be more than 0. 9990 in cases of paternity inclusion and in cases of paternity exclusion, 3 or more loci of exclusion is needed.
