Karyotype of the cyprinid fish Alburnoides bipunctatus (Cyprinidae) from the Tigris River

Chromosome numbers and karyotypes of Cyprinid fish Alburnoides bipunctatus (Bloch, 1782)from the River Tigris were determined by the chromosome preparation technique from uncultured kidney cells. The diploid chromosome number 2n=50, was composed of 8 pairs of metacentric, 11 pairs of submetacentric and 6 pairs of subtelo-acrocentric chromosomes (NF=88). Sex chromosomes were not determined in the this species. The results were briefly discussed with other, previously conducted studies.
