Presentation Transcript

  1. midterm • short answer (choose 13 of 18 for 52 points)

  2. midterm • essay questions (choose 3 of 6 for 48 points)

  3. hardy-weinberg • once we use H-W to show that a population is not in equilibrium, is there any way to show which assumptions are violated? • could the H-W model be used to study genetic diversity corresponding to a phenotype that is controlled by more than one or an interaction of genes?

  4. what’s a species? • biological species concept • phylogenetic species concept

  5. finite population size effects • what is finite population size? what does it result in? why?

  6. population size • what do the terms “small population” and “large population” mean?

  7. mutation and adaptation • how do a species’ genes realize that certain traits are weaker than others? how can a species know it must adapt something such as aspects of its appearance in future generations?

  8. stabilizing selection • what is stabilizing selection? • what is directional selection? • what is diversifying selection?

  9. stabilizing selection

  10. atavistic structures • can alleles lie in a dormant state? • what is an atavistic structure? how is it different from a vestigial structure? • are vestigial structures lost over time?

  11. handicap principle • what is runaway sexual selection? • what is the handicap principle? • does the handicap principle affect fitness?

  12. human-modified selection • does artificial selection lead to in-breeding and homozygosity? wouldn’t this be damaging? • can it be said that humans are having an impact on natural selection and that the loss of biodiversity could be attributed to directly causing extinction as well as indirectly causing loss of species diversity?

  13. human evolution • are humans still evolving? what has modern medicine and technology done to the ability to select out bad traits?
