Genetic drift can also be magnified by natural or human-caused events, such as a disaster that randomly kills a large portion of the population, which is known as the bottleneck effect that results in a large portion of the genome suddenly being wiped out (Select all that apply.) a. bottleneck effect b. random mating effect c. density-dependent effect d. gene flow effect
