The problem of species differentiation of green frogs is connected to the hybrid type of Pelophylax esculentus reproduction. The hybrid has got genes of both parents: Marsh frog Pelophylax ridibundus and Pool frog Pelophylax lessonae. There was established that the four investigated individuals are typical example of hemiclonal inheritance, and their location is not determined by geographical conditions. Based on comparison of genetic and morphological analyses it was ascertained that using F/T index is the optimal way to determine the species of green frog in the field. The accuracy of green frogs’ determination using this index is 70%.
