When surveying the karyotype diversity of European loaches of the genus Cobitis to identify species involved in hybrid polyploid complexes, an extensive polymorphism in number and location of NORs was discovered in C. vardarensis using Ag-staining, C-banding, CMA3-fluorescence and fluorescence in situ hybridization (FISH). This species had 2n = 50, the karyotype contained 13 pairs of metacentric, 10 pairs of submetacentric and two pairs of subtelocentric chromosomes. The NOR-bearing chromosomes… CONTINUE READING
