Answer :
Final answer:
Genetic drift is the change in allele frequency due to random events. The bottleneck effect leads to survivors with altered allele frequencies. Isolated islands experience genetic drift more rapidly than mainland populations.
Explanation:
Genetic drift is the change in allele frequency in a population due to random events. The bottleneck effect occurs when a large portion of a population is randomly wiped out, leading to survivors with different allele frequencies. Due to their smaller size, isolated islands can experience genetic drift more rapidly compared to mainland populations.
