Abstract
A population of Bufo americanus from southwestern Ohio exhibited an extreme degree of transferrin and albumin polymorphism. One hundred and eighty-five individuals were collected from this population, and their transferrin and albumin phenotypes were determined by vertical acrylamide gel electrophoresis. Thirteen transferrin alleles were present in 36 phenotypes, and 11 albumin alleles were present in 29 phenotypes. A deficiency of heterozygotes occurred at both protein loci. The possible mechanisms responsible for the polymorphism and deficiency of heterozygotes are discussed.
