Abstract

Results of a comparative study of the karyotypes of Rana chensinensisand R. arvalis are reported. On the basis of detail morphometrical analysis of each chromosome pair significant karyotype differences were established between two species concerning localization of secondary constriction, the centromere position of 6th chromosome pair and the absolute length of 3 chromosome pairs. The possible mechanisms giving rase to the differences between both karyotypes were discussed. It was suggested that karyotypic divergence of R. arvalis was caused by a pericentric inversion, independent local deletions and transpositions witha consequent amplification of NOR-sites.
