Ötücü Kuşlarda (Passeriformes) Moleküler Cinsiyet Tayini ve Önemi

Öz

Birçok ötücü kuş türünün yetişkinleri eşeysel dimorfizm (yapısal farklılıklar) ve eşeysel dikromatizm (renk farklılığı) göstermemektedir. Bu nedenle morfolojiye dayalı eşey tayini her zaman mümkün değildir. Bununla birlikte geleneksel eşey tayini yöntemleri genellikle üreme dönemindeki yetişkin bireyler için kullanılmakta olup cinsiyeti morfolojik olarak anlaşılamayan yavru kuşlar için kullanılamamaktadır. Moleküler eşey tayini yöntemleri ise geleneksel yöntemlere göre daha kolay ve bireyi öldürmeyen bir seçenek sunmaktadır. Cinsiyet bilgisi davranış ekolojisi, koruma biyolojisi ve populasyon biyolojisi konulu pek çok çalışma için önem arz etmektedir. Bu çalışmanın amacı CHD genleri kullanılarak uygulanan moleküler eşey tayini yöntemi hakkında bilgi vermek, dikkat edilmesi gereken hususları belirtmek ve konunun önemini vurgulamaktır.

Molecular Sexing in Songbirds (Passeriformes) and its Importance

Öz

In many passerine species, adults do not show sexual dimorphism and sexual dichromatism. For this reason, external morphology is not often used for sex determination. Furthermore, traditional sexing methods are often used for adults in reproductive period and cannot be used for nestlings. Molecular sex determination provides an alternative method which is easier than the traditional methods. In this manner, it is very important for many studies on behavioural ecology, conservation biology and population biology. The purpose of this study is to provide information about the molecular sex determination method using CHD genes, to specify matters to be considered and to emphasize the importance of the issue.
