Genetic polymorphism of tetrazolium oxidase in dogs.
Two alleles, To(A) and To(B), determine a genetic polymorphism of tetrazolium oxidase in canine erythrocytes. The approximate gene frequencies for most dog breeds are 0.94 for To(A) and 0.06 for To(B). The gene frequencies' of the German shepherd, 0.8 for To(A) and 0.2 for To(B), differ significantly from those of other breeds. The electrophoretic tetrazolium oxidase isozyme pattern of Canis latrans closely resembles the tetrazolium oxidase A pattern of Canis familiaris.
