Abstract
Three adult local chicken types in Nigeria (Wild type, Ibile; Naked neck ,Abolorun and Frizzled feather, Asaa; and three exotic types; Bovans near, Isa brown and Cobb) were characterized using twenty morphological traits. The descriptive analysis: group means and the standard deviations values of the 20 trits studied showed significant differences for all 20 morphological traits analysed using SPSS 15.0 version. The correlation matrices. dendrogram and Principal Component Analysis (PCA)revealed the exotic types distant from the local types. However, it was observed that the closest neighbour with the local types, 26% coefficient level, was with the naked neck. The Asaa and the Ibile local chicken types show closer level of relatedness (89%0 while Abolorun and the exotics indicated 34% similarity. At 0.90 coefficient level, wattle size comb length, beak length and spur number show some degree of interdependence so also the tail length, shank length, number of toes and wing length clustering together. However, the back length and the height indicate closer interaction between and form a distance relationship with other eight traits. These are indications that the three local chicken types may not fall into same classification and that some morphological traits may influence one another
