Question

which statements are true for both genetic bottlenecks and the founder effect? select the two answers that are co
□ they both drive adaptive evolution.
□ they are both more consequential with larger populations.
□ they both result in a smaller gene pool.
□ they both increase genetic diversity.
□ they both happen by chance.

Explanation:

Genetic bottlenecks (population size reduction) and founder effect (small group colonizes new area) are both random events (chance) that reduce the gene pool size. Adaptive evolution is driven by natural selection, not these; they are more impactful in small populations; they decrease genetic diversity. Thus, the true statements are C and E.

Answer:

C. They both result in a smaller gene pool., E. They both happen by chance.
