Genetic drift (or allelic drift) is the change in the frequency of a gene variant (allele) in a population due to random sampling of organisms.The alleles in the offspring are a sample of those in the parents, and chance has a role in determining whether a given individual survives and reproduces.hen there are few copies of an allele, the effect of genetic drift is larger, and when there are many copies the effect is smaller.
