The First Case of Natural Triploidy in the Mongolian Toad, Bufo raddei

S. N. Litvinchuk, J. M. Rosanov, N. A. Shchepina, V. I. Kazakov, D. V. Skorinov, L. J. Borkin


A triploid female of diploid toad species Bufo raddei was recorded in Buryatia Republic, Eastern Siberia, Russia. Triploidy was identified by means of DNA flow cytometry. The case is recognized as an occasional autotriploidy. No morphological difference was found between triploid and diploid females of the sample.
