Aflood kills most of a population of ants that live near a river. after the flood, the ant population increases, but its allele frequency is different. what type of effect is this?
a. genetic drift
b. mass extinction
c. bottleneck
d. founder

The answer for Apex is "Bottleneck" Which is C.

The answer is: a. Genetic drifts originate from the error, in this case: c. Bottleneck.

Explanation:

Genetic drift, also known as allelic drift is an evolutionary force that acts together with natural selection by changing the allelic frequencies of species over time.

Bottleneck, is that a population undergoes a drastic reduction in its size, giving rise to a population with a high probability of suffering genetic drift. Any mutation in an individual will be amplified in the community when it grows again. Bottleneck events are also characterized by producing a reduction in the genetic diversity of species, due to the extinction of less frequent alleles.

The answer is: a. Genetic drifts originate from the error, in this case: c. Bottleneck.
