Question

what evolves during natural selection
inactivated genes
entire species
the proportions of different traits in a population
the phenotypes of individual organisms

Answer 1

During natural selection, **the proportions of different traits in a population** evolve. Natural selection acts on the phenotypes of individuals within a population, leading to changes in the frequency of certain traits over generations. While individual organisms do not evolve, the collective traits of a population can change as those individuals with advantageous traits are more likely to survive and reproduce. This process can lead to adaptations within the population over time.
