ABSTRACT
OBJECTIVE@#To introduce a new method for calculating the paternity index (PI).@*METHODS@#Assuming that each allele from parents has undergone a transition before it segregates and transmits to child. The transition probability is 1 when parent allele is the same as child's, the transition probability is 0 when parent allele is different from the child's. Every allele has a transmission probability with 0.5. Base on these theories, it is easy to gain the probability that child inherits an allele from the alleged father or mother. Thus, the X value (numerator) and Y value (denominator) of PI formula can be calculated, as unknown man provide an allele for child with the allele frequency.@*RESULTS@#A general formula that calculated the PI for trios, duos and missing child cases was deduced.@*CONCLUSION@#The new method is practical in all kinds of forensic paternity case.
