Answer:
a. bottleneck effect.
Explanation:
A bottleneck effect occurs when some adverse environmental conditions such as typhoons and famine reduce the population size considerably. The allele frequencies of the population are changed. As the population grows again, the gene pool has different allele frequencies than the original population. During population growth, some harmful alleles may become more abundant resulting in a rare disease such as achromatopsia. Therefore, the given population represents the bottleneck effect.
