When the mouse "eyeless" gene was implanted into the fruit flies it switches on the eye development.

Explanation:

The eyeless gene of mouse and fruit fly share a great homology. When Scientists took gene from Mouse and inserted it to fruit fly they observed that it initiated the development of eye at the same spot as the original fruit fly gene does. This implicated that the this gene is highly conserved and fruit fly and Mouse has evolved this gene from same ancestor.  

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
