In our feeding experiment with vermilion/brown and cinnabar/brown mutant flies, we were supposed to use kynurenine or hydroxykynurenine to overcome the enzymatic block in the ommochrome pathway, caused by the vermilion or cinnabar mutations. Which eye color would you expect for each of the two double mutants, if we had supplemented the medium with N-formylkynurenine? Use a diagram of the pathway to explain your answer.
