Question

Quizplus · Accepted Answer

Natural selection occurs when there are differences in the fitness (viability or reproductive success) of individuals with different genotypes. Those with advantageous traits are more likely to survive and reproduce, passing on their beneficial genes to the next generation, while those with less advantageous traits are less likely to survive and reproduce. This nonrandom elimination of genotypes leads to changes in the frequency of alleles in a population over time.
