The Evolution of Populations
Name ____________________
Be sure to study all tables/figures and read the captions
1. Explain how microevolutionary change can affect a gene pool.
2. State the Hardy-Weinberg theorem and describe the usefulness of the Hardy-Weinberg model to population geneticists.
3. List the conditions a population must meet in order to maintain Hardy-Weinberg equilibrium.
4. Explain how genetic drift, gene flow, mutation, nonrandom mating and natural selection can cause microevolution.
5. Distinguish between the bottleneck effect and the founder effect.
6. Explain why even though mutation can be a source of genetic variability, it contributes a negligible amount to genetic
variation in a population.
7. What is the cause of nearly all genetic variation in a population?
8. Explain why the rate of decline for a deleterious allele depends upon whether the allele is dominant or recessive to the
more successful allele.
9. Describe what selection acts on and what factors contribute to the overall fitness of a genotype.
10. Distinguish among stabilizing selection, directional selection and diversifying selection.
11. Give at least four reasons why natural selection cannot breed perfect organisms.
