RESUMO
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.

The genetic polymorphism of eight red cell enzymes was examined in three samples from Gran Canaria and one from Equatorial Guinea. The presence of African genes in the Gran Canaria population showed an African admixture estimated to 6-9%. The genetic distance between Gran Canaria and Equatorial Guinea was 0.033, and that between Gran Canaria and the Spanish mainland only 0.007.
