[Inheritance of parental genomes by a hybrid form Rana "esculenta" (Amphibia, Ranidae)].

In this study, quantitative analysis of paternal genome inheritance by a hybrid form Rana "esculenta" (= Rana esculenta L., 1758 x Rana ridibunda Pall., 1881) (Amphibia, Ranidae) was examined. The hybrid form examined was characterized by a polymodal mode of inheritance (genome of any of the parental species can be inherited). The absence of correlation between the proportion of normal gametes and either sex or ploidity of the producer was demonstrated. The gametes produced could be both haploid and diploid (hybrid or homozygous). The mechanism of alloploid reproduction is discussed.
