BIOL 112 FINAL EXAM REVIEW WITH COMPLETE SOLUTIONS Darwin’s theory of evolution is a strong theory, but at the time of proposing the theory, some aspects were yet to be explained. Which of the following things below did Darwin understand and incorporate i nto his theory? a. That inherited variations could increase an organism's ability to survive and reproduce b. How chromosomes were inherited c. That genetic mutation could be responsible for making new alleles d. That genes were the templates for making pr oteins a. That inherited variations could increase an organism's ability to survive and reproduce As humans use more antibiotics to kill off bacteria, bacteria that are not resistant to antibiotics die off leaving a population of bacteria that are most res istant to antibiotics. This would be an example of which of the following? a. Natural selection b. Allopatric speciation c. Sympatric speciation d. Temporal isolation a. Natural selection On a cladogram (phylogenetic tree), what is the branch point called that comes off first and is believed to be the closest related ancestor to the common ancestor of the group? a. Polytomy b. Sister taxa c. Basal taxon d. Monophyletic taxon c. Basal taxon When DNA is transferred “sideways” between orga nisms, and sometimes species, this would result in which of the following? a. Adaptive radiation b. Vertical gene transfer c. Gametic isolation d. Horizontal gene isolation d. Horizontal gene isolation When calculating allele frequency, if p= 0.55, what is q? a. 0.55 b. 0.45 c. 1.45 d. 0.63 b. 0.45 The potato and the sweet potato are NOT closely related. The potato comes from South America in the region of Peru and Bolivia and is in the nightshade family. The Sweet Potato is in the morning glory family and new research suggests it comes from Asia. The fact that both plants evolved a large starchy root to store energy would be an example of which of the concepts below? a. Analogous structures due to convergence b. Analogous structures due to divergence c. Hom ologous structures due to convergence d. Homologous structures due to divergence a. Analogous structures due to convergence The mouthparts and the antennae of different insects such as the grasshopper, honeybee, the butterfly, and the mosquito are used for different purposes. The grasshopper, for example, primarily bites and chews while the honeybee botes and the butterfly sucks pollen. Though they share a common ancestor, this structure has been modified or enlarged over evolutionary time for the particula r species. This is an example of ___________. a. Homologous structures b. Analogous structures c. Differential structures d. Allopatric structures a. Homologous structures Fanconi anemia is a rare recessive blood disorder found in 1 in 160,000 individuals that leads to an increased risk of leukemia. What would the frequency of the heterozygotes be in the population? a. 0.00499 b. 0.00000625 c. 0.0025 d. 0.0389 a. 0.00499 Which of the following would describe the barrier to gene flow that would happen becaus e insects called cicadas emerge from out of the ground in different years? a. Gametic isolation b. Habitat isolation c. Temporal isolation d. Behavioral isolation c. Temporal isolation When making phylogenetic trees, if you considered the taxa that include d mammals. Which of the following words below would describe having the trait of four legs?
