A rhesus monkey family is described in which a group A offspring was born from a group AB mother and a group B male parent. Discovery of A and O genes in rhesus monkeys indicates that this species of macaques is polymorphic for the A-B-O blood groups, and not monomorphically B, as previously believed.
