Question

When the mouse "eyeless" gene was implanted into the fruit flies, what happened? What implications does this have for the study of evolution?

Answer 1

In this scenario, when the "eyeless" gene from the mouse was taken and implanted into the fruit flies, it resulted in the development of the eye at the same spot as the original fruit fly gene does. This result implies that the gene is highly conserved. The fruit fly and mouse basically have evolved from the same ancestor.
