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. 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
Consistent high expression of Stuft gene in dorsal and ventral portions develops legs in both dorsal and ventral portions. But in this case, in the presence of Chilchees gene expression in the dorsal part develops normal wings and partial development of legs in the ventral surface can be observed.
