Question

when a few individuals start a new colony it most likely results in
a. genetic drift through the founder effect.
b. more variety in the new population.
c. extinction due to the bottleneck effect
d. mutation due to disruptive selection

Explanation:

• Option A: The founder effect is a type of genetic drift that occurs when a small group starts a new colony. Their gene pool is a subset of the original, leading to genetic drift.
• Option B: A small founding group would have less genetic variety, not more.
• Option C: The bottleneck effect is from a drastic population reduction, not founding a colony.
• Option D: Disruptive selection is about phenotype selection, not related to founding a colony causing mutation.

Answer:

A. genetic drift through the founder effect.
