Геміклональне спадкування у зелених жаб: випадковий курйоз, перехідний стан чи закономірний етап розвитку?

Abstract

We propose hypothesis that defines hemiclonal inheritance as a rare natural evolutional way to overcome interspecies hybrid sterility (as well as clonality and polyploidy). The main consequences of hemiclonal inheritance are clonal evolution of genomes and homological interspecies recombination. On the example of hybridogenic Pelophylax esculentus complex we discuss possible reasons and steps of evolution of hemiclonal population systems (HPS). We also discuss unique types of HPS that are typical for the Siverskyi Donets center of diversity of water frogs.
