Leopard frogs (Rana pipiens Schreber) from Colorado were used in laboratory matings to investigate the mode of inheritance of green-brown, dorsal background color polymorphism. A total of 624 F1 progeny were produced in 18 successful matings. The results support the hypothesis that the control of dorsal color in Rana pipens is a two-allele, one-locus system with the allele for green color dominant to the allele for brown color.
