ABSTRACT
The karyotype of the marsh frog Rana ridibunda is consist of 26 chromosomes. These chromosomes are 7 pairs of metacentric and 6 pairs of submetacentric chromosomes. The second pair sex chromosomes, are homomorphic in females and heteromorphic in males. The fundamental number of this species is 52, while the autosomal fundamental number is 48. The tenth pair of this karyotype has a secondary constriction on the long arms of the chromosomes on both sexes.
