ResumoAbstract Utilizing starch gel electrophoresis, a study was made on the albuminlike plasma protein of a tetraploid South American species of frog. No allelic polymorphism at this locus was indicated in the congeneric diploid species O. cultripes , but five distinct electrophoretic phenotypes were encountered among 141 frogs of the tetraploid species O. americanus . These included two homozygous types each with a single distinctive albumin‐like band, and three heterozygous types. The three heterozygotes differed from each other by relative staining intensity of the bands, and presumably represent 3:1, 2:2, and 1:3 ratios of allelic dosage. The frequency distribution of the five phenotypes among 141 frogs fitted well with the expected values calculated on the basis of the binomial (p + q) 4 with allelic frequencies of 0.415 and 0.585.
