19.What are the allele frequencies in the following population: AA = 0.30, Aa = 0.50, aa = 0.20.
20.In what circumstances could one observe strong natural selection yet observe no evolution?
21.What is mutation-selection balance? How might it determine levels of genetic variability in populations?
22.Describe how the Grants estimated heritability of bill depth in the Galápagos’ finches.
23.In your own words (not equations), describe what a correlation measures. What factors can contribute to a correlation between traits? How could a correlation impact evolution?
24.What is the difference between a synonymous and non-synonymous base pair substitution? Describe how this difference may influence evolution.
25.If we discovered “life” on mars, what characteristics would it need to exhibit for it to evolve by natural selection?
