Türkiye’de Myotis myotis (Borkhausen, 1797) ve Myotis blythii (Tomes, 1857) (Mammalia: Chiroptera)’in G-bantlama karyotipleri
Bu araştırma Türkiye’de yayılış gösteren iki sibling yarasa türü, Myotis myotis (Borkhausen, 1797) (Farekulaklı Büyük Yarasa) ile M. blythii (Tomes, 1857) (Farekulaklı Küçük Yarasa)’nin G-bantlamasına dayanmaktadır. G-bantlama karyotipleri iki taksonun aynı G-bantlama gösteren kromozom kollarına sahip olduğunu göstermiştir. G-bantlı kromozomların M. myotis’in M. blythii’den ayrımında yeterli ayırıcı özellik olmadığı tespit edilmiştir.

G-banding karyotypes of Myotis myotis (Borkhausen, 1797) and Myotis blythii (Tomes, 1857) (Mammalia: Chiroptera) in Turkey
This study is based on the G-banding karyotype of 2 sibling bat species Myotis myotis (Borkhausen, 1797) (Greater Mouse-eared Myotis) and M. blythii (Tomes, 1857) (Lesser Mouse-eared Myotis) distributed in Turkey. G-banding karyotypes showed that the 2 taxa possessed identical G-banded chromosome arms. It was concluded that G-banded chromosomes are not sufficient as a diagnostic character for separating M. myotis from M. blythii.Little estimation of the genetic homology of chromosomes can be provided by conventionally stained karyotypes. However, G- and C-banding of chromosomes are the most commonly used techniques in cytogenetic studies for comparison of related taxa (Baker et al., 1987; Qumsiyeh and Baker, 1988). Bickham (1979a, 1979b), Baker (1984), and Baker et al. (1985) determined some cryptic mammal species by using G-banding.
