[Polymorphism for supernumerary chromosomes in populations of Rana temporaria L].
Occurrence of B-chromosomes in four populations of Rana temporaria L. in Minsk, its suburb and Berezinskiĭ biosphere reserve has been studied. The percentage of individuals with B-chromosomes and the average number of B-chromosomes per genome are shown to multiply increase in the population inhabiting for 40 years in the region polluted with waste products. The results obtained are discussed from the standpoint of the action of mechanism for the accumulation of additional chromosomes due to environmental pollution.
