Question

multiple choice question
why can the founder effect cause a previously rare genetic disorder to become common in the new population?
o the allele frequencies in the founding members of the population differ from the allele fre - quencies in the original large population.
o natural selection affects small populations more dramatically than it affects large populations.
o natural selection affects large populations more dramatically than it affects small populations.
o new mutations are more likely to arise in small populations than in large populations.

Explanation:

The founder effect occurs when a small group of individuals separates from a larger population to establish a new population. The genetic makeup of the founding members (allele frequencies) may not be representative of the original large - population. This can lead to the increased prevalence of a previously rare genetic disorder in the new population. Natural selection is not the main factor in the founder effect, and mutation rates are not the key aspect related to the founder effect causing a rare disorder to become common.

Answer:

The allele frequencies in the founding members of the population differ from the allele frequencies in the original large population.
