Question

ChiliCheese and Stuft are two maternal gene proteins that establish the dorsal/ventral axis of the developing X mutans. Chilicheese levels are highest at the dorsal surface of the animal while Stuft is highest at the ventral surface; both proteins exist as a gradient. In X. mutans, legs typically protrude from the ventral surface while wings protrude from the dorsal surface. What physical features would you expect to see in an X. mutans individual where the Stuft expression was consistently high in both dorsal and ventral portions of the animal? Explain your answer.

Explanation / Answer

According to the information, the Stuft is responsible for ventral expression of legs. Also, the expression levels of Struft are either absent or exceedingly low in the dorsal surface.

Thus, in mutants with high density of Stuft expression in both dorsal and ventral surface, structural deformities in the expression and development of wings and legs will take place. This will be accompanied with either no or deformed structural expression and development of the legs and wings since neither of the genes will be at their appropriate spatial location in the developing organism.
