“…Although native chickens represent a fundamental animal genetic resource in Nigeria, they have remained largely genetically uncharacterized and unimproved ( Oluyemi and Roberts, 2000 ). The Fulani and Yoruba ecotypes have been studied for morphological and morphometrical surveys ( Osaiyuwu et al., 2009 ) and for characterization based on breeding systems ( Momoh et al., 2010 , Sola-Ojo et al., 2012 , Sola-Ojo et al., 2013 , Ige and Salako, 2014 ). The available genetic studies concern only the characterization of adaptive genes ( Ojo, 2002 , Fayeye et al., 2006 , Fayeye and Oketoyin, 2006 ) and not the identification of genetic diversity among populations.…”
