STUDY GUIDE Campbell 8th edition BIO 311D CHINNERY CHAPTER 23 Important figures 8th edition: 23.5, 23.6, 23.7, 23.8, 23.9, 23.10, 23.13, 23.16, 23.17, 23.18 Important terms: microevolution, macroevolution, population, species, gene pool, Hardy-Weinberg theorem, Hardy-Weinberg equation, Hardy-Weinberg equilibrium, allele, genotype, phenotype, gamete, homozygote, heterozygote, mutation, point mutation, duplication, genetic drift, bottleneck effect, founder effect, natural selection, gene flow, genetic variation, directional selection, stabilizing selection, disruptive selection, heterozygote advantage, frequency-dependent selection, intraspecific sexual selection, interspecific sexual selection. Knowledge goals: Be able to discern between a population and a gene pool. Understand the Hardy-Weinberg theorem – what the symbols stand for, how they represent portions of a gene pool (p + q = 1), and be able to answer questions about specific populations.

Unformatted text preview: Why are we learning the Hardy-Weinberg equation? What is its importance in the study of evolution? Discuss some of the main causes of variation. What is natural selection? Describe genetic drift, and contrast bottleneck events with the founder effect. What is an animals’ fitness? What is stabilizing selection? Which phenotypes are at an advantage with this mode of selection? What is directional selection? Which phenotypes are at an advantage with this mode of selection? What is disruptive selection? Which phenotypes are at an advantage with this mode of selection? Describe how a balanced polymorphism in a population can exist. What is the heterozygote advantage? How does it relate to fitness? Describe frequency-dependent selection. What does sexual dimorphism have to do with sexual selection?...
