Abstract

An unusual triploid individual (3N=42) was found in a population of Rana neba in nature. The individual had triplets of 14 chromosomes, which are apparently identical to those of diploid R. neba. This strongly suggests that this individual is autotriploid, although the mechanism of its emergence remains an open question.
