Which of the following is not true of natural selection?(a) natural selection acts to preserve favorable traits and eliminate unfavorable traits (b) the offspring of individuals that are better adapted to the environment will make up a larger proportion of the next generation (c) natural selection directs the course of evolution by preserving the traitsacquired during an individual’s lifetime (d) natural selection Test Your Understanding acts on a population’s genetic variability, which arisesthrough mutation (e) natural selection may result in changes in allele frequencies in a population
