Question

Which one of these processes describes bottleneck effect? Group of answer choices

Answer 1

Answer:

Sudden change in environments that alters gene frequency of a population

Explanation:

The bottleneck effect is a genetic drift that happens when the size of a population is suddenly reduced for at least one generation, this can be triggered by a natural disaster. This sudden change leads to a decrease in genetic variation, as the population decreases the frequency of different alleles changes leading to a completely new population that may or may not be able to adapt. In the image, I added you can observe how the bottleneck effect works.

Considering this information we can conclude that the correct answer is "sudden change in environments that alters gene frequency of a population".

I hope you find this information useful and interesting! Good luck!
