Abstract

NOR phenotypes were determined and compared in the population of Carp Cyprinus carpio L.1758 belonging to Cyprinidae family living in Beyler and Germeçtepe dam lakes Kastamonu . NORs are located through the short arm of the large one none/homologue submetacentric or arms of the metacentric chromosome for Beyler population. NORs located on two none/homologue submetacentrik or acrocentric chromosomes, in terminal position on the short arm for Germeçtepe population. Heteromorphism for NOR size was observed in two populations, NOR number per genom was two.

KASTAMONU BEYLER VE GERMEÇTEPE BARAJI’NDAKİ Cyprinus carpio L.,1758 POPULASYONLARININ KARŞILAŞTIRMALI NOR FENOTİPİ

Abstract

Beyler ve Germeçtepe Barajı‘nda Kastamonu yaşayan Cyprinidae familyasından Cyprinus carpio L.1758 populasyonlarının NOR fenotipi belirlenerek karşılaştırılmıştır. NOR’ lar Beyler Barajı populasyonunda büyük bir çift homolog/homolog olmayan submetasentriğin kısa kolu boyunca veya metasentrik kromozomun kolları boyuncadır. Germeçtepe Barajı populasyonunda ise bir çift homolog/homolog olmayan akrosentrik veya submetasentrik kromozomun kısa kollarında terminal olarak yerleşmiştir. İki populasyonun NOR büyüklüğü bakımından heteromorfik farklılıklar gösterdiği belirlenmiştir, genom başına düşen NOR sayısı ikidir. Böbrek dokusundan elde edilen kromozomlar pH = 6.8’lik fosfat tamponunda hazırlanmış giemsa ile boyanmıştır. “One-Step” metoduna göre NOR bölgeleri belirlenmiştir.
