Step 1
The founder effect occurs when a small group of individuals establishes a new population, leading to a change in allele frequencies. The bottleneck effect occurs when a population undergoes a sudden reduction in size, leading to a change in allele frequencies. Show more…

Which of the following statements about genetic drift is true? a. The founder effect requires a physical barrier between an older population and a newly founded populations. b. Genetic drift requires a large effect event such as a bottleneck effect or founder effect. c. Bottleneck effects decrease genetic variation, but founder effects increase genetic variation. d. In the absence of other evolutionary forces, genetic drift ultimately leads to fixation or loss of alleles regardless of population size.
