2. Imagine a combination of microevolutionary mechanisms other than mutation/se- lection. How do you think these mechanisms would act in concert? What variables would need to be considered in a combined model of the mechanisms you have chosen? Draw a hypothetical graph of the change in allele frequency over time. Hint: You have to set some starting parameters to make your graph. Optional: To learn more about microevolutionary mechanisms in the real world, read The Beak of the Finch by Jonathan Weiner. It's a popular press (easy to read) book about some of the most effective research into microevolutionary mecha- nisms ever done.

Discuss the role of mutation in the origin of genetic polymorphisms. Suppose that a genetic polymorphism involves two alleles at frequencies of 0.45 and 0.55. Describe three different scenarios to explain these observed allele frequencies. You can propose that the mutations that produced the polymorphism are neutral, beneficial, or deleterious.
From the figure (specifically the slope of the imaginary trend line), what is the general relationship between mutation rate and genome size?
You sample DNA from seven bighorn sheep from a population of 2,000 in the Rocky Mountains of Colorado. You sequence 10,000 basepairs from an intron in a diploid coat color locus. You think the SNP mutation rate is somewhere around 10-3 per generation for the whole locus. How many SNPs do you expect to find?
For three years, Gunther Schlager and Margaret Dickie estimated theforward and reverse mutation rates for five loci in mice that encodevarious aspects of coat color by examining more than 5 million mice forspontaneous mutations (G. Schlager and M. M. Dickie. 1966. Science151:205–206). They detected the following numbers of mutations at thedilute locus: Gametes examined Mutations detectedForwardmutations 260,675 5Reversemutations 583,360 2 Calculate the forward and reverse mutation rates at this locus. If thesemutations rates are representative of rates in natural populations of mice,what would the expected equilibrium frequency of dilute mutations be?
Part 1: Describe the differences in SNP diversity and LD structure observed between African and non-african populations. Part 2: Explain why these differences are expected from the evolutionary history of modern humans. Part 3: How do these differences impact association studies in terms of SNP array design and identifying causal variants at significant loci?
n class we investigated the reason cystic fibrosis is maintained in the human population in higher frequency than we expected given the deleterious effects of being homozygous at the CFTR gene. We calculated the actual mutation rate of the CFTR gene to be 6.7 x 10-7. The mutation rate expected under mutation-selection balance was 4 x 10-4. What is the most plausible explanation as to why cystic fibrosis is maintained in the human population at a higher frequency than we expect? a. Negative selection against the CFTR deleterious alleles is too weak to eliminate the alleles from the human population. b. Positive selection for the CFTR deleterious alleles is likely occurring in response to some other selective pressure in the human population, possibly resistance to typhoid fever. c. The CFTR gene has an exceedingly low mutation rate causing humans to have no genetic variation at that gene. d. The CFTR gene has an exceedingly high mutation rate and that is…
With the information that a Wright- Fisher population have a size of 10,000 and assume that mutation rate is 2.5x10-8 per site per generation. What is the probability of difference between the two sequences that were randomly taken from the population? Show all working and explanation.
Explain why we use both Giemsa and DAPI when studying human genetics, and not just one or the other. How are they similar, and how are they different?
Achondroplasia is a form of dwarfism that is inherited in humans as an autosomal dominant disorder. A survey in a small country showed that, within a two-year period, there were 24 children with normal parents born with this disorder out of a total of 16,789 births. What is the mutation rate in mutations/locus/generation? answer to the nearest 0.0001.
Given what you read about the human genomein Chapter 13, would you predict that most mutations in humansare harmful, beneficial, or neutral?
