I was given 2 images of embryos which look very similar. One is a chick and the other is a human. It's not required to see them. Questions:
1. The embryos look very similar. Does this mean they have very similar DNA?
2. How could you test the above?
3. By altering the hormal/environmental conditions of either embryo, could you turn it into another kind of embryo?

First helpful answer gets 10 points..
