title: [New data on the genetic structure of dimorphic populations of the common hamster (Cricetus cricetus L.)].
abstract: Long-term (1965-1974) Mendelian crossbreedings of two coloured forms (black and red) of Cricetus cricetus, carried out by the author, have shown that dominant melanistic mutation exists in a homozygous state. Thus, it is proved experimentally that natural population of C. cricetus consisting of black and red individuals is a dimorphous one by the phenotype and a polymorphous one by the genotype. The structure of the population includes the black homozygotes (genotype AA), black heterozygotes (genotype Aa) and red recessive homozygotes (genotype aa). All three forms are fully fertile and give quite viable and fertile progeny.
