You continue your experiments with the sepia mutation on chromosome III. You cross the reciprocal translocation strain to the sepia pure line to generate F1 flies that are both translocation heterozygotes and Ss heterozygotes. As before, you testcross F1 males and females in two separate experiments. Cross F1 males x pure sepia females (Note: There is no crossing over in the F1 males.) F1 females x pure sepia males (Note: Crossing over may occur in the F1 females.) F2 Progeny 1/2 sepia, fully fertile 1/2 wild-type, semi-sterile 497 sepia, fully fertile 493 wild-type, semi-sterile 4 sepia, semi-sterile 6 wild-type, fully fertile What can you conclude from these results? Select the three correct statements.
