WebThis means genetic drift driven allele frequency change is faster in smaller populations than in large populations. The final outcome of genetic drift is allele elimination/fixation. Overall genetic drift leads to reduction of heterozygosity. Prediction: Genetic drift drives genetic differentiation between geographically isolated populations. WebEventually, genetic drift can cause a subpopulation to become genetically distinct from its original population.
