Examine the figure below, which shows how Hox genes affect the development of the fly body plan. Consider the gene Dfd (dark blue), which directs the development of mouthparts. 1) What do you predict will happen if Dfd is expressed in the thorax instead of Scr (yellow)? (Scr directs front leg development.) 2) Will this occur because Dfd regulates the expression of other genes? Explain your answer. 3) Why are Hox genes important in animal development?
