Answer

By transferring the mouse Pax6 gene and switching out the fly eyeless gene, Gehring observed that the eyes developed at different sites on the transgenic flies. He concluded that a gene that controls the development of a mammalian eye can be transplanted to control the development of the insect eye, demonstrating how the "genetic toolkit" remains constant throughout most animal groups.
