In Drosophila, the Recessive Allele P, When Homozygous, Determines Pink

Multiple Choice

In Drosophila, the recessive allele p, when homozygous, determines pink eyes.Pp or PP results in wild-type eye color.On the same chromosome of Drosophila that carries the p (pink eyes) locus there is another locus that affects the wings.Homozygous recessives, byby, have blistery wings, whereas the dominant allele By produces wild-type wings.The P and By loci are very close together on the chromosome; that is, the two loci are tightly linked.For the cross PPbyby  ppByBy, what phenotype(s) would appear in the F₂ generation if crossing over occurred?

A) Wild-type eyes/blistery wings and pink eyes/wild-type wings
B) Wild-type eyes/wild-type wings and pink eyes/blistery wings
C) Wild-type eyes/wild-type wings, wild-type eyes/blistery wings, and pink eyes/wild-type wings
D) Pink eyes/blistery wings, pink eyes/wild-type wings, and wild-type eyes/blistery wings
E) Wild-type eyes/wild-type wings, wild-type eyes/blistery wings, pink eyes/wild-type wings, and pink eyes/blistery wings
