20. A recessive lethal allele has achieved a frequency of 0.22 due to genetic drift in a very small population. Based on natural selection, how would you expect the allele frequencies to change in the next three generations? Note: Your calculation can assume that genetic drift is not altering allele frequencies in either direction.

Give one example of how allele frequencies change from one generation to the next due to mutation, migration, genetic drift, nonrandom mating, and selection.

13. With regard to genetic drift, are the following statements true or false? If a statement is false, explain why. a. Over the long run, genetic drift leads to allele fixation or loss. b. When a new mutation occurs within a population, genetic drift is more likely to cause the loss of the new allele rather than the fixation of the new allele. c. Genetic drift promotes genetic diversity in large populations. d. Genetic drift is more significant in small populations.
