37) Adaptive evolution within a single patient’s body to the drug AZT would be slowed when, a) The HIV’s generation time is increased b) The HIV’s population size is increased c) The mutation rate of HIV is decreased d) The body size of HIV is decreased e) Answers a & c , are both correct 38) In ten years HIV genes evolve, within the population of individuals infecting a single patient, to the same degree that humans have evolved in

39) Based on the data presented in class for bacteria infecting a human population, substantial resistance to a new antibiotic can be expected to occur as fast as 40) A new influenza pandemic occurs, Two genotypes (A & B) of an annual asexual lizard are transported on a floating log to an isolated island. Genotypes A produces green lizards and genotype B produces yellow lizards. The lizards hatch in the spring, grow to adulthood by summer, and then lay a clutch of eggs in a nest and die. An evolutionary biologist follows the fate of 1000 hatchlings (just emerged from the egg) that she found and tagged during a survey of the island: Phenotype Spring hatchlings in year-1 Summer adult lizards in year-1 hatchlings (in year-2) produced per adult lizard in year-1 Green 200 100 8 Yellow 800 200 6 41): The population as a whole is: a) Increasing by 60% d) Decreasing by 70% b) Increasing by 100% e) At equilibrium c) Decreasing by 40% 42): The Darwinian fitness of the Green genotype is: 43): In the Spring of year-2, the frequency of the Yellow genotype in the genotype pool is:

44): In general, the best gene transport machine is: 45): In General evolution, evolution occurs because: a) Genotypes with higher survival are the fittest b) Genes that code for phenotypes that leave more offspring in the next generation accumulate in the gene pool c) Phenotypes that code for genotypes that are better gene transport machines are favored by natural selection d) Genotypes with higher fecundity are the fittest e) Both answers (a) and (d) are correct

"Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
