A fly that is heterozygous at three loci is testcrossed to a fly with black eyes, bent wings, and hairy legs. The 1000 offspring shown below are obtained from this cross: red eyed, straight winged, smooth legged                 8 black eyed, bent winged, hairy legged                       12 black eyed, straight winged, smooth legged             39 red eyed, bent winged, hairy legged                           41 red eyed, bent winged, smooth legged                       354 black eyed, straight winged, hairy legged                  366 red eyed, straight winged, hairy legged                      93 black eyed, bent winged, smooth legged                    87   (1) What is the phenotype of a fly that is heterozygous at all three loci?

In fruit flies, the red eye allele (pr+) is dominant to the purple eye allele (pr) and the normal wings allele (vg+) is dominant to vestigial wing allele (vg). These loci are located on the same chromosome. A pure breeding red-eyed fly with vestigial wings was crossed with a pure-breeding purple-eyed fly with normal wings. All of the F1 progeny had a WT phenotype. Which of the following represents the arrangement of alleles on the F1’s chromosome?
