title: A new approach to the computation of indices of paternity.
abstract: This paper describes an algorithm to calculate several indices of paternity (combination frequency, paternity likelihood (Y/X) and paternity exclusion probability (E) for father-mother-child combination (trio) as well as father-child combination (duo). This program is written in FORTRAN IV and applicable to any kinds of blood group systems such as Rh and HLA. The characteristic points of the present method are as follows: First, the relation between genotypes and phenotypes is given in a straightforward way by introducing a translational matrix. Secondly, by a unit run on a computer, several indices of paternity are tabulated for all kinds of combinations of trio as well as duo. Finally, the efficiency of diagnosis of a certain system is listed by calculating the distribution of log (Y/X).
