1. What happens to the allele being tested? Is it fixed or lost? Over many generations or just a few? 2. Run the simulation again with the same settings. Do you get the same results? Explain.

3. Now try changing the population size. Run the simulation with populations of 100, 500, and 1000. How is the allele frequency affected?

4. Suppose the initial frequency of a desired allele is less than 0.5. Set the initial frequency to 0.1 and run the simulation for different-sized populations. What happens to the allele frequency?

5. Make a prediction about how the allele frequency will be affected if the initial frequency is greater than 0.5.

6. Now try running the simulation with the initial frequency set at 0.9. How is the allele frequency affected?
