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.

Özet

Bu çalışmada Orta Anadolu Cricetulus migratorius ve Meriones tristrami’ deki Nükleolar Organizatör Bölgeler (NORs)’in dağılımı incelenmiştir. Cricetulus migratorius’un karyotipinde diploid kromozom sayısı, temel kromozom sayısı ve otozomal kromozomların temel sayısı sırasıyla 22, 44, 40’dır. Meriones tristrami’ nin diploid kromozom sayısı, temel kromozom sayısı ve otozomal kromozomların temel sayısı ise sırasıyla 72, 84, 80’dir. Cricetulus migratorius’da nükleolar organizatör bölgeler metasentrik ve subtelosentrik otozom çiftlerinin telomerik bölgelerinde tespit edilmiştir. Ayrıca, Meriones tristrami’nin metasentrik ve akrosentrik otozomlarındaki terminal nükleolar organizatör bölgelergösterilmiştir.
