  1. Question 1

    Q1. A population of animals has a high rate of genetic drift due to a bottleneck event. What is the primary effect of this increased genetic drift?

    • A) Increased genetic variation
    • B) Decreased genetic variation
    • C) No effect on genetic variation
    • D) Fixation of beneficial mutations

    Answer: Decreased genetic variation

    Explanation: Increased genetic drift leads to decreased genetic variation, unlike increased genetic variation.
