Twо genes in fruit flies, which аffect bristle length аnd bоdy cоlor, аre 12 map units apart. These two genes are not X-linked. A cross was made between a true-breeding fruit fly with normal bristles and yellow body and a true-breeding fly with short bristles and a gray body. All F1 offspring had normal bristles and gray bodies. The F1 female offspring were then crossed to male flies with short bristles and yellow bodies. A. (4 points) What would be the possible phenotypes of the F2 offspring? B. (6 points)What would be the phenotypes of the F2 recombinant offspring? Explain how you know this. C. (6 points) If 300 F2 offspring are born, how many would you expect to have short bristles and a gray body?
