Refer to the table above and then answer the questions that follow.
-Genetic drift results in a change in gene frequencies because:
A) the population size is so small that chance occurrences can alter gene frequencies.
B) reproduction is nonrandom within the population.
C) gene flow within the population is less than gene flow between populations.
D) the population has not yet stabilized.

Quizplus · Accepted Answer

Genetic drift refers to random fluctuations in the frequencies of alleles within a small population. This randomness can lead to significant changes in gene frequencies over time, as certain alleles may become more or less common purely by chance, rather than due to natural selection or other evolutionary forces.
