Distribution of qualitative traits within and between two populations of Nigerian local chickens ecotypes
The study was conducted at Akpehe poultry farm, Makurdi. Nigeria. 1700 local chickens belonging to the Tiv and Fulani ecotypes were used for the study. The study was designed to provide information on the distribution of qualitative traits within and between the ecotypes. The distribution of each qualitative traits was measured on the parent populations as well as on their generations. These were computed as the ratio of their frequencies to the total number of birds. Qualitative traits varied within and between the ecotypes. There were indications of qualitative traits modification for adaptation to climatic challenges. Solid black and black colored related plumages and body pigmentations colors were abundant among the Tiv ecotypes. Color patterns with the capacity to repel radiant heat had higher frequencies in the Fulani ecotypes. There were high distribution of single comb type within and between the ecotypes. Solid black and other black-related plumages and body pigments birds can survive among the Tiv ecotypes populations but not within the fulani ecotypes populations. While the Fulani ecotype can survive within the Tiv ecotypes populations.
