Problem: Which of the following statements about genetic drift are true?a. Genetic drift occurs more slowly and has a greater effect in small populations, as compared to large populations.b. Genetic drift is the change in the frequency of an allele in a population that occurs because of random chance.c. Genetic drift can only impact existing alleles and reduces allelic variation in a population.d. Genetic drift is the change in the frequency of an allele in a population that occurs because the allele provides a reproductive advantage.

Recall: Genetic Drift - change in the frequency of an allele over time


a. Genetic drift occurs more slowly and has a greater effect in small populations, as compared to large populations.

TRUE. Allele frequencies in a population change slowly and over time and maybe more observable in small populations.
