Expert Answer:

True.

Genetic drift is the random fluctuations in the frequency of the appearance of a gene in a small isolated population, presumably owing to chance rather than natural selection. Accidents in small populations can change the frequency of some genes in a population, even if they give no survival advantage. This is the notion of genetic drift, which provides diversity without any adaptations.
