Here's a pretty good link to help you learn more about population genetics and Hardy-Weinberg. It's called the "Gene School"

Microevolution by Genetic Drift

Define Genetic Drift.

Distinguish between bottleneck and founder effect. (be familiar with both)

Microevolution (continued)

Carefully learn and appreciate gene flow. You'll need this in speciation.

See how hard it is to form a new species if gene flow continues between two populations?
