Both the loci for red eyes and normal wings are located on the same chromosome within Drosophila.

Both the loci for red eyes and normal wings are located on the same chromosome within Drosophila. Using a standard dihybrid test cross design, you produce a heterozygous F1 female by crossing a homozygous female for red eye, normal wing (RR DD) against a homozygous male for white eyes and downward wings (rr dd). This F1 female is crossed against a white eyes and downward wing male (rr dd) and 1000 progeny are scored. Is it possible to get the following result? Explain your answer.

red eye, normal wing; 171

red eye, downward wing; 325

white eye, normal wing; 364

white eye, downward wing; 140
