Unformatted text preview: population is most likely to be the first to lose allelic diversity (in other words, which population is likely to reach fixation first?)? a) Population W b) Population X c) Population Y d) Population Z e) Impossible to predict with information given here 7 29. You are studying a single gene with two alleles (A and a) in a population. You find that the frequency of A changes from 0.4 to 0.7 in one generation, and perform some basic calculations. The χ2 statistic is greater than 5 for both generations (remember the critical value is 3.841). The 95% confidence interval for one generation of drift is (0.25, 0.55). You estimate that s = 0.5 and Ne = 10. Given this information, what should you conclude? a. The population is not in HWE because χ2 > 3.841. Drift alone cannot explain the change in allele frequencies because 0.7 lies outside the 95% confidence interval. Selection overrides drift because Nes>>1. This all assumes that there is no migration and mutation. b. The population is not in HWE because χ2 > 3.841. Drift alone cannot explain the change in allele frequencies because 0.7 lies outside the 95% confidence interval. Selection overrides drift because Nes>>1. This all assumes that there is random mating as well as no migration and mutation. c. The population is not in HWE because χ2 > 3.841. Drift alone cannot explain the change in allele frequencies because 0.7 lies outside the 95% confidence interval. Drift overrides selection because Nes>>1. This all assumes that there is random mating as well as no migration and mutation. d. The population is not in HWE because χ2 > 3.841. Drift alone cannot explain the change in allele frequencies because 0.4 lies outside the 95% confidence interval. Drift overrides selection because Nes>>1. This all assumes that there is no migration and mutation. e. The population is not in HWE because χ2 > 3.841. Drift alone can explain the change in allele frequencies because 0.7 lies outside the 95% confidence interval. Drift overrides selection because Nes>>1. This all assumes that there is random mating as well as no migration and mutation. 30.
