Genetic Drift - the constant changing of allele frequencies (that percentage of all alleles any one, or more, allele occupies in a population) in a population over time, due to random mating. Random Mating - has the effect of changing how frequently an allele is found in a population. GENETIC DRIFT IS RANDOM, ALWAYS DRIFTING UP AND DOWN bottlenecks - where a gene pool is significantly reduced for some reason and a relatively small allele diversity remains. Founder event/effect - a cha...
