Abstract

Conventionally stained karyotype and Ag-NOR banded chromosomes of a male red fox Vulpes vulpes L., 1758 from Kırıkkale province in Turkey were determined. The chromosome set included 16 biarmed auto- somal pairs with two dot- like B chromosomes 2n= 34 + 2B, NF=67, NFa=64 . The X chromosome was a large metacentric and the Y was a small acrocentric, almost similar in size of the Bs. The Ag-NOR regions were found in the telomeric regions of the long arm of three medium-sized metacentric autosomes.

Orta Anadolu’daki Kızıl Tilkinin Karyotipi ve B-Kromozomların Varlığı

Abstract

T ürkiye’deki Kırıkkale ilinden erkek bir kızıl tilki Vulpes vulpes L., 1758 ’nin standart boyanmış karyotipi ve Ag-NOR bantlı kromozomları tespit edilmiştir. Kromozom setinde iki nokta benzeri B kromozomu ile beraber 16 iki kollu otozomal çift yer almaktadır 2n= 34 + 2B, NF=67, NFa=64 . X kromozomu büyük metasentrik, Y kromozomu ise hemen hemen B kromozomların büyüklüğünde küçük akrosetriktir. Ag-NOR bölgeler orta büyüklükteki üç metasentrik otozom çiftinin uzun kollarının telomerik bölgelerinde tespit edilmiştir
