C-Heterochromatin and nucleolus organizer region distribution of Myotis emarginatus Chiroptera: Vespertilionidae from Turkey

In this study, the banded karyotypes C- and Ag-nucleolus organizer regions NORs of Myotis emarginatus in Turkey were determined for the first time. The karyotype contained 44 chromosomes, the number of chromosomal arms NF was 54, and the number of autosomal arms NFa was 50. Slight C-heterochromatic blocks were observed in the centromeric regions of some autosome pairs, whereas the sex chromosomes were euchromatic. The Ag-NORs were detected in the short arms of a large and a medium-sized acrocentric autosome. The distribution of C-heterochromatin regions in Turkish populations of M. emarginatus is similar to those reported in some other Myotis species.
