Genetic drift in a population affects the gene pool in which of the following ways?
Understand the Problem
The question is asking how genetic drift influences the gene pool within a population, specifically which of the provided options accurately describes this effect.
Answer
Decrease in genetic variation.
The final answer is decrease in genetic variation.
Answer for screen readers
The final answer is decrease in genetic variation.
More Information
Genetic drift can result in the loss of certain alleles, decreasing genetic diversity within a population, which is crucial for adaptation and survival.
Tips
A common mistake is confusing genetic drift with gene flow, which involves the transfer of alleles between populations and can increase genetic variation.
