Farmer Joe has black chickens and purchases a white rooster. Black and white genes in chickens are codominant. Draw Punnett squares to predict the offspring of the black chickens and white rooster.

Use capital "B" for black and capital "W" for white.

1.) What is the genotype of the black chickens?
________________
2.) What is the genotype of the rooster?
_________________
3-4-5.) Genotypic ratio: BB:__ BW:__ WW__

6-7-8.) Phenotypic ratio: Black :___ Black and White:__ White__

9.) If Farmer Joe wanted HALF of the chicken offspring to be black and HALF of the chicken offspring to be Black AND White, what genotype would the rooster have to be that he purchased? ___________
