6.. In a type of bird color on the feathers is controlled by two different genes F and S. FF Ff ff SS Ss FF birds make black pigments, Ff gray pigment, and ff no pigment, resulting in white feathers. Another gene controls how the pigment is applied to the feathers. SS birds have color on the whole feather, Ss feathers are speckled with white, and ss have all white feathers. You cross FFss birds to ffSS birds. SS
