In fruit flies, red eyes are dominant to green
eyes. In a cross between a short-winged,
green-eyed fly and a long-winged, red-eyed
fly, the results were as follows:
40 percent short winged and red eyed
10 percent short winged and green eyed
10 percent long winged and red eyed
40 percent long winged and green eyed

In the above example the red-eyed, longwinged
fly had chromosomes best represented
as:

(A) L R

(B) l L
R r

(C) L l
R r

(D) L R

(E) l r
