Chromosomal polymorphism of Bufo bufo: Karyotype and C-banding pattern of B. b. verrucosissima

  • V. J. Birstein
  • A. L. Mazin


Bufo bufo verrucosissima has a karyotype consisting of 22 chromosomes (6 pairs of large and 5 pairs of small chromosomes which are meta- and submetacentric). By means of Ag-AS-staining nucleolar organizers were localized in the telomeric region of the long arms of the 6th pair of chromosomes. The karyotype differs from those of the other B. bufo subspecies by the form of the 4th pair, which is metacentric. A slight chromosomal polymorphism was shown also after C-banding of B. b. verrucosissima and B. b. bufo chromosomes.
