Hybrid form Pelophylax esculentus-ridibundus (Amphibia, Ranidae) from the Tisa river drainage: its origin and evolutionary potential

Morozov-Leononv S.Yu.

SUMMARY. The genetic variability of the hybrid form Pelophylax esculentus-ridibundus and its parental species (P. ridibundus) of the Tisza River basin  was analyzed. The decrease in the level of the inherited genome variability within the hybrid form in comparison with the parental species was demonstrated. A more significant divergence between the hybrid form samples than between the marsh frog samples was found. No correlation was found between the species composition of the hybrid population of the population and the level of genetic variability of the hybrid form. The evolutionary perspectives of clonal and hemiclonal forms of hybrid origin are discussed.

Key words: i>Pelophylax, hybrid form, hemiclone diversity, hemiclonal inheritance, evolutionary potential
