Question

A flood 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

Answer 1

Answer:

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.

Answer 2

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