Choose the pathway that most accurately describes how evolution might select for increased antibiotic resistance in a bacterial population exposed to an antibiotic. Bacteria are exposed to an antibiotic. > The antibiotic causes differential reproductive success. > Differential reproductive success increases genetic variation. > Increased genetic variation changes gene frequencies. Bacteria are exposed to an antibiotic. > The antibiotic causes an increase in genetic variation. > Genetic variation causes changes to gene frequencies. > Changing gene frequencies cause differential reproductive success. A bacteria population has genetic variation. > Bacteria are exposed to an antibiotic. > The antibiotic causes differential reproductive success. > Differential reproductive success leads to changes in gene frequencies. A bacteria population has genetic variation. > Genetic variation causes differential reproductive success. > The antibiotic kills individuals with low reproductive success. > Genetic variation in the population increases
