Studies on Metatherian Sex Chromosomes VII. Glucose-6-phosphate Dehydrogenase Expression in Tissues and Cultured Fibroblasts of Kangaroos

Abstract

Expression of the sex-linked enzyme glucose-6-phosphate dehydrogenase (G6PD) was examined electrophoretically in tissues and cultured fibroblasts of female kangaroo heterozygotes ranging in age from 26 days post part urn to adult. All tissues expressed only the maternally derived allele irrespective of which allele was maternal or paternal in origin.
