- QUESTION 26 When thinking about changes in allele frequencies over time, why do you care more about the effective population size rather than the census (total number of individuals) population size?QUESTION 31 You are examining a population that has recently been subject to artificial selection for larger filet size (body size) through selective breeding in a commercial fishery. The artificial selection took quite a few generations, but the researchers were eventually successful. Which of the following statements is most likely true? a. There is likely no correlation between parent and offspring filet size (body size). b. The population experiencing artificial selection always has higher fitness than wild populations. c. The offspring of the selected population will, on average, be larger than the wild populations. d. The filet size (body size) of the fish is most likely controlled by a single gene.QUESTION 8 In a certain population of rabbits, 25 new rabbits are born and five move into the population from surrounding areas during a single year.

The decrease in the northern herd's population is explained by its inability to migrate and the park's decreasing carrying capacity. B. The fact that bison only migrate in years of deep snow indicates that they have exceeded the park's carrying capacity. C. The carrying capacity for other animals found in Yellowstone has increased due to the bison's migration outside of the park. D. The movement of bison beyond park boundaries is not due to the bison population being too large for the park's carrying capacity.
