Over generations, what happens to the frequency of advantageous alleles in a population?

In a population over successive generations, advantageous alleles typically increase in frequency due to natural selection. When individuals within a population possess alleles that confer a beneficial trait, they are more likely to survive, reproduce, and pass these alleles on to their offspring. As a result, these advantageous alleles become more common in the gene pool over time.

This process can lead to the adaptation of the population to its environment as the traits associated with the advantageous alleles improve the chances of survival and reproductive success. In contrast, alleles that do not confer such benefits may be selected against and decrease in frequency. Hence, the correct answer reflects the dynamic nature of evolution where beneficial traits proliferate, aligning with the principles of natural selection.
