Oocytes from individuals heterozygous for the X-linked glucose-6-phosphate dehydrogenase (G6PD) electrophoretic variants, types A and B, were examined for their G6PD pattern. Three bands were observed, A, B, and AB; the presence of the AB (hybrid) band demonstrates that both X-linked G6PD alleles are functional in the maturing human oocyte.
