multiple choice question\nwhat changes in the genetic variation of a population are expected after it experiences a bottleneck followed by growth and a return to the original population size?\ngenetic variation will be decreased.\ngenetic variation will be increased.\nthe amount of genetic variation will be the same.\nneed help? review these concept resources.
Answer
Brief Explanations:
A population bottleneck is a sharp reduction in population size. During this event, many alleles are lost from the gene - pool. Even if the population later grows back to its original size, the genetic variation remains low because the alleles that were lost during the bottleneck are not easily regained.
Answer:
Genetic variation will be decreased.
