I agree. The key here is to actually discuss what the numbers mean - which
is what the student was asking in the first place. Lets have some input of
how large the human / chimp genome really is or how many genes there are.
Lets hear some mathmatical computations regarding what that 98% really
stands for. What is the significance of the 2% and how many genes are
included in it?
