Genetic drift is a change in allele

WebGenetic drift is random change in allele frequencies due to sampling effects in finite populations. Essentially, because some individuals no longer contribute alleles to the gene pool, due to random death or other reasons preventing reproduction, genetic drift causes random changes in allele frequencies over generations. ...
