In Crane flies there is a gene Y that codes for body colour. The yellow body allele is dominant to the grey body allele for that gene. A second gene W on a different chromosome codes for wing shape. For this gene, the Wrinkled allele is dominant to the straight allele. You cross a female crane fly that is heterozygous for the body colour allele and has straight wings with a male crane fly that has a Yellow body (homozygous) and is heterozygous for the Wing gene. What are the expected phenotypes and their ratios in the offspring from this cross? a. Yellow Wrinkled: Yellow Straight: Grey Wrinkled: Grey Straight of 1:1:1:1 b. Yellow Wrinkled: Yellow Straight of 1:1 c. None of the other answers have the correct ratios d. Yellow Wrinkled: Yellow Straight: Grey Wrinkled: Grey Straight of 9:3:3:1 e. Yellow Wrinkled: Yellow Straight: Grey Wrinkled: Grey Straight of 3:3:1:1
