Question Answer
genetic drift a random change in the frequency of alleles within a populations gene pool which can happen very quickly in small populations
founder effect a geographically isolated area has a non-representing sample of alleles from a parent populations
bottlenecks causes by major disaster which kills off most of the population and there is a random chance of which alleles survice so the allele frequency is altered
