Another type of monohybrid inheritance involves the expression of both phenotypes in the heterozygous situation. This is called codominance. One of the best-known examples of codominance occurs in the blue Andalusian chicken. "Blue" birds are heterozygous (BW) and result from the mating between a black bird (BB) and a white bird (WW). Blue birds do not really have blue feathers, instead having a mixture of black and white feathers that reflects light to appear blue. Thus, the "blue" coloration is not a consequence of blending of the pigments (after all, the mix is not gray) but rather the result of both colors existing on the same bird. That is both phenotypes occur on the same individual. a. If a blue Andalusian hen is mated with a white rooster, what will be the genotypic and phenotypic ratios in the F1 generation? Genotypic ratio- Phenotypic ratio- b. List the parental genotypes of crosses that could produce at least some: White offspring- Black offspring
