In fruit flies, curved wings are recessive to straight wings, and ebonybody is recessive to gray body. A cross was made between truebreeding flies with curved wings and gray bodies and flies withstraight wings and ebony bodies. The F1 offspring were then mated toflies with curved wings and ebony bodies to produce an F2 generation.A. Diagram the genotypes of this cross, starting with the parentalgeneration and ending with the F2 generation.B. What are the predicted phenotypic ratios of the F2 generation?C. Let’s suppose the following data were obtained for the F2 generation:114 curved wings, ebony body105 curved wings, gray body 111 straight wings, gray body114 straight wings, ebony bodyConduct a chi square analysis to determine if the experimental dataare consistent with the expected outcome based on Mendel’s laws.
