Karyological studies of the 2n=60 cytotype of Nannospalax nehringi from Central Anatolia

Abstract

In this study, the G-bands and nucleolus organizer regions (NORs) of the 2n = 60 chromosomal form of Nannospalax nehringi from Central Anatolia (Konya) are presented. The karyotype possesses nine pairs of submetacentric and subtelosentrics and 20 pairs of acrocentric autosomes gradually decreasing in size (fundamental number = 80 and autosomal fundamental number = 76). NORs were localized in the telomeric regions of the short arms of three large pairs and one medium-sized pair of subtelocentric autosomes (nos. 1, 3, 4, 9).
