Chapter 22, Problem 2
Why isn't inbreeding considered an evolutionary process? a. It does not change genotype frequencies. b. It does not change allele frequencies. c. It does not occur often enough to be important in evolution. d. It does not violate the assumptions of the Hardy–Weinberg principle.

In what sense is the Hardy–Weinberg principle a null hypothesis?
Why is genetic drift aptly named? Select True or False for each statement. T/F It causes allele frequencies to drift up or down randomly. T/F It occurs when alleles from one population drift into another. T/F It occurs when mutations drift into a genome.
True or false? Gene flow can either increase or decrease the average fitness of a population. Explain.
Evaluate this statement: Gene flow increases the genetic divergence of populations.
