Abstract :In the present study, the 2n = 54 chromosomal race of blind mole rats, Nannospalax xanthodon superspecies, from Kırıkkale Province in Turkey was investigated. Conventional chromosome staining, Ag-NOR insert ignore into journalissuearticles values(Nucleolus Organizer Region); staining, and C-banding analysis were carried out on specimens of mole rats. The karyotype including 3 metacentric pairs insert ignore into journalissuearticles values(nos. 1-3);, 3 submetacentric pairs insert ignore into journalissuearticles values(nos. 4-6);, 3 subtelocentric pairs insert ignore into journalissuearticles values(nos. 7-9);, and 17 acrocentric pairs insert ignore into journalissuearticles values(nos. 10-26); of autosomes insert ignore into journalissuearticles values(NFa = 70);. C-heterochromatin regions were found in the centromeric and pericentromeric region and the short arms of some bi-armed autosomal pairs, and C-heterochromatin was localized in pericentromeric areas of a few acrocentric autosomes. The X chromosome has a centromeric C-positive band and the Y chromosome appeared to be uniformly and C-negatively stained. In all of the specimens studied the NORs were localized in distal heterochromatin areas of the short arms of 4 pairs insert ignore into journalissuearticles values(nos. 4, 5, 8, 9); of biarmed autosomes.
