How Does Genetic Drift Affect Small Populations Differently Than Large

question 2

Multiple Choice

• A) Smaller populations can be transformed into large ones if genetic drift is sufficiently nonrandom.
• B) Since genetic drift is a random effect, it has the same outcome in large and small populations.
• C) An entire trait and its underlying genetic basis can disappear from a small population quickly, but may be maintained in a large population.
• D) Since there are many instances of a rare trait in the large population, it is more likely to be selected out, and disappear, in that larger population.
