In the Fruit Fly Drosophila melanogaster, wings (A) are dominant over a lack of wings (a) and red eyes (E) are dominant over sepia (brownish) eyes (e). A wingless fly that is heterozygous for eye color is crossed with a fly that is heterozygous for both eye color and presence of wings. What are the genotype and phenotypic ratios for this cross? What fraction of the offspring from this cross will be wingless and have sepia eyes? What fraction will have the genotype AaEe?
