Andalusian chickens have one allele for white feathers and one allele for black feathers – they display codominance. When they are crossed the heterozygous offspring have black and white checkered feathers (BW). Pure chickens are either black (BB) or white (WW). Cross an Andalusian (heterozygous) chicken with a white chicken. Make a Punnett Square on a piece of paper that will help you answer the question. What percentage of the offspring will be black? What percentage of the offspring will be white? What percentage of the offspring will be andalusian?
