Abstract :The present study reports the banding patterns insert ignore into journalissuearticles values(G- and C-banding); of chromosomes of Cricetulus migratorius from Central Anatolia. Karyotype of C. migratorius comprised insert ignore into journalissuearticles values(2n); 22 chromosomes. The number of chromosomal arms insert ignore into journalissuearticles values(FN); was 44 and the number of autosomal arms insert ignore into journalissuearticles values(FNa); was 40. Subtelocentric X and Y chromosomes were very similar in size, but they differed on G- and C-banding patterns. Most autosomes in this species were C-negative. Pair no. 4 had very small centromeric C-bands, autosome no. 8 possessed an under-centromeric heterochromatin block, and the distal part of chromosome no. 9 had a C-positive band. The Y chromosomes had an entirely heterochromatic long arm. The X chromosome possessed a very large under-centromeric block of heterochromatin.
