Question

1. a forest with several different species of rabbits had a huge fire that killed most of the different populations of rabbits allowing only a small, random assortment of survivors to escape to a different area. this is an example of which one of these terms? marks : 1.00 a. genetic drift e. a and c c. bottleneck effect b. founder’s effect d. a and b

Explanation:

1. Bottleneck Effect (C): The fire drastically reduced the rabbit population, leaving a small random group. This matches the bottleneck effect (a population bottleneck from a disaster, reducing genetic variation).
2. Genetic Drift (A): Genetic drift includes random changes in allele frequencies, and the bottleneck effect is a type of genetic drift (due to the random survival of a small group).
3. Why Others Are Incorrect:

• Founder’s Effect (B): Involves a new population from a small group colonizing a new area, but here the survivors escaped (not founding a new population from scratch in the same way).
• Options D (A and B) and others are invalid as B does not apply. Thus, A (genetic drift, as bottleneck is a type of it) and C (bottleneck effect) both apply, so E is correct.

Answer:

E. A and C
