When a population exhibits adaptation, it indicates that the population has responded to a pressure from the environment in a way that causes the prevalence of beneficial features to rise over time.
Natural selection only affects heritable traits in populations, favoring advantageous alleles and reducing the frequency of harmful alleles, a process known as adaptive evolution. Natural selection only affects heritable traits in populations. However, natural selection affects whole organisms rather than specific alleles. A person may have a genotype that is extremely advantageous and a phenotype that, for example, boosts fecundity, but if that person also contains an allele that causes a fatal childhood ailment, the fecundity phenotype won't be passed on to the next generation.
