When there is low gene flow
Genetic drift is a major factor in evolution that refers to random changes in allele frequencies in a population over time. It can result in the loss of genetic diversity and the fixation of certain alleles, leading to evolutionary changes. In small populations, genetic drift can have a significant impact on the genetic makeup of the population.
When there is low gene flow.
Gene drift tends to be a major factor in evolution in small populations, where random fluctuations can have a larger impact. It is particularly important in cases of genetic bottleneck or founder effect, where a small group establishes a new population with reduced genetic diversity, leading to increased susceptibility to gene drift.

When there is low gene flow (apex 10.1.2)
Genetic drift basically is the reduction of genetic diversity where certain genes are selected through random chance. Founder or bottleneck events are the major ones. Those certain genes may or may not be beneficial.
When there is low gene flow
Yes. Genetic drift-- the change in allelic frequencies of a population due to chance-- can play a major role in evolution. The effects of drift are most pronounced in small, isolated populations. Drift can bring alleles to fixation very quickly in such populations, and can lead to genetic differentiation between them, possibly contributing to speciation.
Which of what? I can't answer your question if it's vague like this.
