What is the map distance between B and S? You must show and clearly label ALL work to receive credit.
3:Consider the map distance you just calculated in the previous question. If a green abdomen, bent antenna double mutant fly was crossed with a wild type, and you then used their offspring for a testcross, what phenotypic ratio would you expect to see in the F2? (You must show and clearly label ALL work in order to receive credit.
