In a certain breed of chickens, a white hen and a black rooster were mated. All of the offspring had white feathers on the tops of their bodes and black feathers below. Which statement is the best explanation of how that genetic information was transmitted? A. The alleles for white feathers were dominant to the alleles for black feathers.
B. The alleles for black feathers were dominant to the alleles for white feathers.
C. The alleles for black feathers were incompletely dominant to the alleles for white feathers and so a blend of the two traits was expressed.
D. The alleles for white feathers were codominant to the alleles for black feathers and so both alleles were expressed together.
