Molecular sexing approach using CHD marker for monomorphic birds of Gunung Ledang, National Park, Johor / Jessey Angat

Many conservation centers in Malaysia have presented serious problem in sexing monomorphic birds as it does not possess any noticeable morphological differences between sexes. Therefore, it is very hard for them to establish the breeding strategies, conservation and management programs. Polymerase C...
