You are studying a group of Oregonian beavers, and you are interested in the population genetics of a single locus. You genotype 100 beavers and discover that for your locus of interest, there are 55 A¹A¹ homozygotes, 20 A¹A² heterozygotes, and 25 A²A² You estimate that the frequency of the A¹ allele is ["0.65", "0.35", "0.20"]         and that the expected number of A¹A² heterozygotes under Hardy-Weinberg equilibrium should be [ "12.25", "45.5", "50"]

Several haploid strains of Saccharomyces cerevisiae grow well on YPD but do not grow on minimal media unless adenine is added to the minimal media. Some of those strains accumulate a red pigment and, thus, produce red or pink colonies. How would you determine the biochemical pathway that is defective in these yeast strains? How would you assign the functions to the genes that are mutated in these strains?

How is the body affected by Asthma? Explain in detail the cells, organs, organ systems affected by Asthma.

What are some of the best cognitive tests for regular people and why?

what's the relation between teratomas and ES cells, and the experiments to show their similarity

Compare the phenotypic variation seen in Mendelian inheritance, incomplete dominance, codominance, epistasis, and polygenic inheritance.

Suppose you return to the population after 10 generations and observe 80 black, 240 brown and 180 tan individuals. Explain how you would use the H-W model to determine if there has been statistically significant evolutionary change (change in genetic composition) in the population. Include the following terms in your answer: null hypothesis, observed and expected genotype frequencies, chi-square. Recall that you would need to do the chi-square calculation using observed and expected numbers of individuals of each genotype, not using observed and expected frequencies.

11. What is the theory of fixed species? Explain why fossils represented a problem for this theory. Briefly state why the theory of fixed species predominated for such a long period of history.

12. Describe Lamarck’s explanation for the evolution of species. Were his hypotheses eventually supported or rejected? Explain how his observations played a role in the study of evolution.

13. What are Darwin’s major contributions to the theory of evolution?

14. Explain how the fossil record and homologous structures are evidence for evolution.

15. Which of the following is evidence for common ancestry: analogous or homologous structures? What are some examples of each?

16. Explain how phylogenetic/evolutionary trees are created and what they represent. Know how to interpret them! What do the branch points represent?

17. Define natural selection. Make sure to address how mutations contribute to it. Then give some examples.

18. Define a population. Compare that to a community and ecosystem. What do each of these categories include?

19. Describe genetic drift. How is this different from selection? Does it usually occur in small or large populations?

20. Distinguish between the following concepts: a. the bottleneck effect and the founder effect b. directional selection, disruptive selection, and stabilizing selection c. artificial selection and natural selection.

What is your best estimate of the rate of de novo somatic mutations? On what studies do you base your estimate? Explain the method(s) used in those studies and the assumptions on which the numbers are based.

What factors (for example, age, sex, temperature, cell type, environmental exposure, etc.) affect the rate of de novo somatic mutations in humans?
