Abstract: The distribution of nucleolar organizer regions (NORs) in Cricetulus migratorius and Meriones tristrami from Central Anatolia was determined. In the karyotype of Cricetulus migratorius the diploid number, fundamental number, and fundamental autosomal number are 22, 44, and 40, respectively. The diploid number, fundamental number, and fundamental autosomal number of Meriones tristrami are 72, 84, and 80, respectively. In Cricetulus migratorius, NORs occur in the telomeric regions of metacentric and subtelocentric autosome pairs. Furthermore, terminally located NORs in metacentric and acrocentric autosomes of Meriones tristrami are presented in this present paper.
