An incompletely dominant gene controls the color of chickens so that BB produces black, Bb produces a slate-gray color called blue and bb produces spalhed white. A second gene controls comb shaped with dominant gene (R) producing a rose comb, and a recessive gene (r) producing a single comb. If a pure-breeding black chicken with a rose comb is mated to a splashed white chicken with a single comb. In the F2 Generation, what fraction of the offspring will be black with rose comb? Show all punnett squares.
