The correct answer is: A.It can cause random fluctuations in allele frequencies

Explanation:

Genetic drift refers to random changes in allele frequencies in a population, and it has a stronger effect in smaller populations. In small populations, these random fluctuations can lead to significant changes in allele frequencies over time, sometimes resulting in the loss of alleles or the fixation of others, simply due to chance rather than selective pressure.

Let’s break down the other options:

B.It has no effect on allele frequencies: T...
