Questions

1. In each experiment, what was the reaction in the frequencies of each of the other two genotypes over the generations to the negative selection pressure against the homozygous recessive? Explain

2. At each level of negative selection pressure, about how long do you think it would take to eliminate the allele for white fur completely?

3. Analyze the four graphs which you have made based on the four sets of data. Make a generalization about the relationship between the rate of decrease of the genotype and the level of the negative selection pressure against that genotype.

4. Given the population of Maine mice in this simulation, suggest a scenario in which the dominant allele would become the allele of lesser frequency in the gene pool.

5. If for some reason heterozygous individuals were selected against, predict what would happen to the frequencies of the homozygous members of the population.

6. Explain how natural selection can be said to "drive" evolution.

7. Describe other factors which contribute to the process of evolution.
