Probability of Paternity in Rh Blood Groups

Abstract

SUMMARYA method of calculating the probability of paternity, based upon Bayes' theorem, for Rh blood groups has been developed. Tables have been prepared for calculation of the probability of paternity for the most common levels of testing, i.e., with five anti-sera (anti-C, -D, -E, -c, -e), with four (anti-C, -D, -E, -c) and with three (anti-C, -D, -E). The same probabilities at other levels of testing can be calculated by applying the method and tables presented in this paper. Since the tables presented herein include calculations for chromosomes which appear to occur but rarely as far as known to date, these tables can be applied to all populations with different chromosome frequencies.The author wishes to thank Prof. S.
