Correlation of paternity index with probability of exclusion and efficiency criteria of genetic markers for parternity testing

The statistical correlation between the chance of paternity exclusion and paternity index is explored to derive a new criterion of judging the efficiency of an array of genetic determinations for parentage diagnosis. The theoretical basis is illustrated with allele frequency data on genetic markers used in a paternity testing protocol to examine the possible effects of changing the genetic systems on the prospect of identifying fathers by genetic markers.
