Several fly mutations are called vg(vesigial) black (b) and pr (purple). Vg affects the wings, b the body color and pr the eye color. The wild type allele is denote by + (ex. vg+) and the mutant allele with just its name (ex. vg). You perform the following cross: vg b pr / vg b pr  X vg+ b+ pr+ / vg+ b+ pr+. What are the genotypes and phenotypes of the offspring of this cross?
