A computer-assisted population frequency study of 14 polymorphic blood grouping systems in North Carolina.

Results of a population frequency study conducted on 14 polymorphic blood grouping systems in the North Carolina white and black populations are reported. A microcomputer program has been developed to facilitate the handling and storage of the large volume of data generated during the two years it took to complete this study. This computer program was also designed to calculate the combined phenotypic frequency for a given set of blood types.
