Chapter 19, Problem 15TYU
Summary Introduction
To explain: The study of the genetic contribution to disease in populations of Finland or Iceland is much easier as opposed to that of the United States.
Introduction: A genetic disease or disorder can result from deviations or abnormalities in the genetic makeup of an organism. These abnormalities in the genome can be caused as a result of Mutations. These mutations when passed down across generations lead to the development of disease or disorder.

Genetics is commonly seen as being grouped into several general areas: transmission, molecular, and population/evolution. Which biological processes are studied in transmission genetics?
Steven Frank and Laurence Hurst argued that a cytoplasmically inherited mutation in humans that has severe effects in males but no effect in females will not be eliminated from a population by natural selection because only females pass on mtDNA (S. A. Frank and L. D. Hurst. 1996. Nature 383:224). Using this argument, explain why males with Leber hereditary optic neuropathy are more severely affected than females.
How can we detect recent strong selection in the human genome? Explain using the recent positive selection of the lactase persistence allele in some human populations.

- Microbiologists have discovered that alleles associated with antibiotic resistance are present in bacteria that live in soil, even in environments that are comparatively free of antibiotic pollution from human activities. Why are such alleles present (albeit at low levels) in bacterial populations? Conversely, if resistance alleles are beneficial, why are they rare in natural populations of bacteria?arrow_forwardSome populations change noticeably in form within a hundred years. If only one gene in every 200,000 mutates and if most mutations are harmful, how is such change possible?arrow_forwardScientist sampled a population and the homozygous dominant genotype was 36% for disease X. What is the frequency of the heterozygotes in the population?arrow_forward
- In hospitals where many tuberculosis patients are treated the population of the tuberculosis mycobacteria may be constituted of multiresistant (to antibiotics) strains. How does the synthetic theory of evolution explain this fact?arrow_forwardAs evolution is the change in allele frequency in a population over time … Explain the evolution of bacteria in terms of changes to the frequency of the NDM-1 gene.arrow_forwardExamining Table 20-4, what do you think would be theorder of mutations fixed during selection in a third evolving virus line?

- The delta-32 mutation, a recessive gene, gives humans protection from HIV infection. The allele frequency in a town in Sweden is 20%. What percent of the population have two copies of the gene and are therefore immune to HIV? What percent of the population are less susceptible to the disease since they are heterozygous?arrow_forwardHow did human farming influence the evolution of the sickle cell allele in human populations?arrow_forwardIn regards to HIV resistance allele and the incidence of AIDS is a population, answer the following: Q: In terms of a change in net mutation rate, what would happen if the mutation rate from the resistant to non-resistant allele was increased, or vice versa?

- Apply the VIDA table to the evolution of sickle cell disease to justify whether it is an instance of evolution by natural selection. Answer the following questions. Is there variation in this trait in the population? How exactly does it vary? Is the trait at least partly inherited? Is there selection for this trait in a particular environment? (What is the selective pressure? And how does a trait give an advantage or disadvantage in that environment?) What is the evidence that this trait makes organisms better adapted to their environment?arrow_forwardIt has been claimed that “evolution repeats itself.” Whatis the evidence for this claim froma. the analysis of HbS alleles?b. the analysis of antibiotic resistance in bacteria?c. the analysis of experimentally selected bacteriophageφX174?d. the analysis of Oca2 mutations in cave fish?e. the analysis of stickleback Pitx1 loci?arrow_forwardNatural selection means that the environment favors survival of some genotypes.
