Karyotypes of some Cypriniform fishes from the water bodies of Armenia

Karyotypes of six species of Cypriniformes from the water bodies of Armenia—blackbrow Acanthalburnus microlepis , white bream Blicca bjoerkna transcaucasica , chub Leuciscus cephalus orientalis , stone moroco Pseudorasbora parva , mursa Barbus mursa , and Angora stone loach Barbatula angorae were studied. The karyotype of A. microlepis is represented by 50 chromosomes (2n = 50), 10M + 28SM + 12STA, NF = 88; of B. bjoerkna transcaucasica , by 2n = 50, 12M + 24SM + 14STA, NF = 86; of L. cephalus orientalis , by 2n = 50, 12M + 18SM + 20STA, NF = 80; of P. parva , by 2n = 50, 8M + 16SM + 26STA, NF = 74; of B. mursa , by 2n = 100, 6M + 36SM + 58STA, NF = 142; and of B. angorae , by 2n = 50, 8M + 24SM + 18STA, NF = 86. The intraspecific and interspecific chromosome polymorphism of species of the genera Blicca, Leuciscus and Pseudorasbora is described.
