You are studying two traits in fruit flies: eye color where there are two colors, brown and red, and wing shape where there are straight and curled phenotypes. you mate two flies that are heterozygous for the genes that control both of these traits and get the following phenotypes in the following ratio: 9 red eyed and straight wings; 3 red eyes and curled wings; 3 brown eyes and straight wings; 1 brown eyed and curled wings.
