In chickens, a dominant hereditary abnormality (e.g., creepers) causes death when the genotype is homozygous (CC). The recessive condition (cc) at this locus produces a normal phenotype. Another gene locus with co dominant alleles is known to govern feather color such that the genotype FF = black, f = splashed white, and Ff = blue. Also, a completely dominant gene W produces white skin. Yellow skin is produced by the homozygous genotype ww. a. In CeFWw x CeFWw, what proportion of the live progenies is a.1 Ceffww a.2 nomal, blue feathered, white skinned a.3 ccFfWw
