Abstract excerpt

Two paternity cases involving black persons are reported in which possible paternal exclusions existed if the A2B red cell phenotype represented the genotype A2B. ABH transferase assays were performed to determine if the A2B phenotypes arose from the genotype A1B or A2B. These assays confirmed that all group A members carried the A1 gene and not the A2 gene. Therefore, the alleged father was not excluded in...
