Документ Inheritance of parental genomes by a hybrid form Rana “esculenta” (Amphibia, Ranidae)(Russian Journal of Genetics, 2009) Morozov-Leonov, S.Yu.; Mezhzherin, S.V.; Nekrasova, O.D.; Shabanov, D.A.; Korshunov, A.V.; Krutyak, F.F.In this study, quantitative analysis of paternal genome inheritance by a hybrid form Rana “esculenta” (= Rana esculenta L., 1758 × Rana ridibunda Pall., 1881) (Amphibia, Ranidae) was examined. The hybrid form examined was characterized by a polymodal mode of inheritance (genome of any of the parental species can be inherited). The absence of correlation between the proportion of normal gametes and either sex or ploidity of the producer was demonstrated. The gametes produced could be both haploid and diploid (hybrid or homozygous). The mechanism of alloploid reproduction is discussed.Документ A case of natural triploidy in European diploid green toad (Bufo viridis), with some distributional records of diploid and tetraploid toads(Russian Journal of Herpetology, 2007) Borkin, L.J.; Shabanov, D.A.; Brandler, O.V.; Kukushkin, O.V.; Litvinchuk, S.N.; Mazepa, G.A.; Rosanov, J.M.A triploid female (3n = 33) was found in diploid species Bufo viridis from the Crimea Peninsula, Ukraine. The case is recognized as an occasional autotriploidy. No morphological differences were found between this triploid female and other diploid specimens of the sample. Three categories of triploids in the Bufo viridis group are classified. Based on six green toad samples identified by chromosome number, the distribution of diploid and polyploid toads in Kazakhstan is discussed.Документ Mass occurrence of polyploid green frogs (Rana esculenta complex) in Eastern Ukraine(Russian Journal of Herpetology, 2004) Borkin, L.J.; Korshunov, A.V.; Lada, G.A.; Litvinchuk, S.N.; Rosanov, J.M.; Shabanov, D.A.; Zinenko, A.I.Первое сообщение об обнаружении Северско-Донецкого центра разнообразия зеленых лягушек
