摘要: 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 0.06 To(B). frequencies' the German shepherd, 0.8 0.2 differ significantly from those other breeds. electrophoretic isozyme pattern Canis latrans closely resembles A familiaris.
