Which one of these processes describes bottleneck effect? group of answer choices
alleles transferred to the next generation in portions that differ from previous generation
chance events that change allele frequency sudden change in environments that alters gene frequency of a population transfer of alleles in and out of a population due to movement of fertile individuals

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!
