B) population size decreases
C) mutation rate decreases
D) population size increases
E) random mating increases

Question

Quizplus · Accepted Answer

Genetic drift has a larger impact on smaller populations because random changes in allele frequencies are more likely to have a significant effect when the number of individuals is limited. In larger populations, these random changes are less likely to significantly alter allele frequencies due to the law of large numbers.
