Abstract:
Since the information supplied by the paternity testing of alleged parents was less than that of standard triplet parentage testing,so the paternity index (PI) calculating methods of standard triplet parentage testing was not suitable for calculating the PI value of alleged parents.In order to establish a more precise method for calculating PI value of alleged parents with STR typing results,the first thing is to summarize the standard triplet PI calculating formulas according to the Essen Mller theory.These formulas are 1/p,1/2p,1/p+q,1/2p+2q.This article reports a new PI calculating method in case of paternity testing of alleged parents.Compared with other methods,the new method for calculating Y value either considering random man and random female or considering the alleged father(mother)and random female(man).
