question 234

Multiple Choice

Two populations of raccoons are similar in most respects, but the population on the east side of a river is much smaller than that on the west side.There is little gene flow between the populations.Which statement about these populations is most accurate?

• A) The population on the west side of the river should experience more fluctuations in allele frequency due to genetic drift.
• B) The population on the east side of the river should experience more fluctuations in allele frequency due to genetic drift.
• C) The population on the west side of the river should have more fluctuations in allele frequency because it will experience a higher mutation rate.
• D) The population on the east side of the river should have more fluctuations in allele frequency because it will experience a higher mutation rate.
• E) The populations should experience similar degrees of fluctuations in allele frequency because mutation and genetic drift should affect them in the same way.
