Q1. Propose a female fly with brown eye colour (keep all other traits as wild type) and design a male fly with ebony body colour (keep all other traits as wild type). Mate the two flies. Examine the F1 offspring from this cross.
Q2. In many countries, conservationists are trying to design national park systems so that "islands" of natural area (the big parks) are connected by thin "corridors" of undisturbed habitat. The idea is that this arrangement will allow animals and plants to migrate between refuges. Why would such migration be significant?
