Genetic drift is the change in the relative frequency in which a gene variant (allele) occurs in a population due to random sampling. That is, the alleles in the offspring in the population are a random sample of those in the parents.
someone correct me if I'm wrong but this is what I think of: Gene flow is when you introduce or remove alleles because of individuals enter or leave population (Think: alleles flowing in and out). Genetic drift is the RANDOM change in allele frequency in a population.ene flow tends to reduce genetic variation between these to populations, but increase it overall. Notice, @LookingForASpot, that you are saying a small group from a population (very important).. Genetic drift is a change in gene frequency due to statistical (chance) fluctuations in a finite population.
