1- What two evolutionary agents are most responsible fordecreases in gentic variation in a population ?

2- How can selection cause two populations to become differentwith time ?

3- what effect would increasing gene flow between twopupulations have on their genetic makeup ?

4- Through what mechanism can new gentic information beintroduced into a poulation?

5- What is the fgate of most new mutaions?

6- Descibe how the effects of directional selection may beoffset by gene flow ?

7- What is the difference between bottleneck effect and the founder effect?
