Unformatted text preview: 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: a) 0.25 d) 4 b) 0.5 e) 8 c) 1.0 43): In the Spring of year-2, the frequency of the Yellow genotype in the genotype pool is: a) 0.1 d) 0.6 b) 0.2 e) 1.0 c) 0.5 44): In general, the best gene transport machine is: a) Phenotype with the highest survival d) Genotype with the highest fecundity b) Phenotype with the highest fecundity e) Phenotype that replicates the most copies c) Genotype with the highest survival of its genotype 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 46) A pharmaceutical drug that binds to which molecule (making it unavailable to a virus) would prevent the HIV virus from entering a CD4 + helper T-cell a) Reverse transcriptase b) CD4 protein c) CCR5 protein cofactor d) Both answers b & c e) None of the above 47) 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 48) In ten years HIV genes evolve, within the population of individuals infecting a single patient, to the same degree that humans have evolved in a) 50 years b) 100 years c) 500 years d) 1,000 years e) 1,000,000 years 49) 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 a) One month b) 6 months c) 1 year d) 10-15 years e) Only after hundreds of years 50) A new influenza pandemic occurs, a) When a hybrid virus is produced that carries some genes from a farm animal virus and some from a human virus b) When humans are infected by a strain of influenza virus that normally infects birds c) When humans are infected by a strain of influenza virus that normally infects swine d) Usually at intervals of 10 to 30 years e) Both answers a & d are correct A researcher discovers a new micro-virus that has only one haploid gene.
