Questions
1. Define, population genetics, gene pool, alleles and genetic variability.
2. State the five conditions required for Hardy-Weinberg equilibrium.
3. Describe the significance of the Hardy-Weinberg principle as it relates to evolution.
4. Define each term and then describe how nonrandom mating, mutation, genetic drift, gene flow, and natural selection alter allele frequencies in populations.
5. Define p, q, p2, q2, and 2pq in the Hardy-Weinberg equation.
6. Given data, use the Hardy-Weinberg equation to determine the frequencies of two alleles, and of the genotypes they produce, hence to predict the percentage of the population that is homozygous dominant, heterozygous, or homozygous recessive for that trait.
7. State how mutation and genetic recombination provide the variation needed for evolution to occur.
8. Describe how each of the following mechanisms affects the genetic variability of a population: natural selection, genetic drift (including the founder effect and bottlenecks), and gene flow.
9. Explain how each of the above mechanisms leads to evolution (i.e., a change in allele frequencies) in a population.
10. Use a graph with an example to demonstrate stabilizing, directional, and disruptive selection.
11. Define sexual selection and give one example.
