Contribution of diploid and triploid hybrid frogs in maintenance of studied R-E systems. a Crossings of triploid hybrid females with RRL genotype and diploid hybrid males led to appearance of P. ridibundus and diploid P. esculentus tadpoles. Triploid hybrid females produced haploid eggs with P. ridibundus genome while diploid hybrid males produced haploid sperm with either P. ridibundus or P. lessonae genomes. b Crossings of two diploid hybrid frogs led to appearance of triploid tadpoles with RRL and LLR genotypes, P. ridibundus tadpoles and diploid P. esculentus tadpoles. Diploid hybrid females produced diploid eggs with both P. ridibundus and P. lessonae genomes, and haploid eggs with P. ridibundus genome. Diploid hybrid males presumably produced haploid sperm with either P. ridibundus or P. lessonae genomes
