AUTOSOMALLY DETERMINED POLYMORPHISM OF GLUCOSE-6-PHOSPHATE DEHYDROGENASE IN PEROMYSCUS.
Glucose-6-phosphate dehydrogenase commonly occurs in at least two forms in most tissues of the deer mouse, Peromyscus maniculatus, as demonstrated by starch-gel electrophoresis. An autosomally determined genetic polymorphism in one of the enzymes was discovered. A hybrid molecule occurs in the heterozygote; this suggests a dimeric structure of this enzyme.
