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
splashed white. A second gene controls comb shape,
with the dominant gene R producing a rose comb and
r producing a single comb. If a pure-breeding, black
chicken with a rose comb is mated to a splashedwhite
chicken with a single comb in the F2
generation, what fraction of the offspring will be
blue with single comb?
a. 9/16
b. 3/8
c. 3/16
d. 1/8
e. 1/16
