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.

Genetic drift is an important factor in evolution when small populations experience random fluctuations in allele frequencies due to chance events. This can lead to the loss of genetic diversity and fixation of certain alleles, impacting the overall genetic makeup of the population. Genetic drift is particularly significant in small, isolated populations or during founder events.
Evolution is not a cause of genetic change: it is the effect of genetic change.
Natural selection is the most significant factor in the evolution of an organism. It drives the process by selecting for traits that best suit an organism to its environment, leading to the accumulation of advantageous genetic variations over time.
