Natural Spontaneous Autotriploidy in the Genus Pelophylax (Anura: Ranidae)

S. N. Litvinchuk, D. V. Skorinov, J. M. Rosanov


Two triploid individuals of diploid green frog species Pelophylax cerigensis and P. cretensis were recorded in Rhodes and Crete islands (Greece). Triploidy was identified by means of DNA flow cytometry. The cases are recognized as a natural spontaneous autotriploidy. In P. cretensis incidence of triploidy was 10.0% per sample and 6.7% per species, in P. cerigensis 5.6% per sample and species.
