Blood group polymorphisms in the Canary Islands.

Abstract

Human samples from the seven Canary Islands were studied for the following polymorphic red cell blood group systems: ABO, RH, MNSs, FY and P. In contrast to the intra-insular homogeneity found, inter-insular heterogeneity was observed for ABO, RH and FY. The observed blood group allelic systems were within the range of European populations, with some minor African contribution.
