The attached picture shows how bacteria gain antibiotic resistance. Firstly, a few individuals attain a
beneficial mutation in their genetic material that accords them the capability to survive in an antibiotic. The
individuals are hence able to survive and
reproduce more than those individuals without the mutation. There is, therefore, a genetic
shift in the population in favor of the resistant genotype. After generations, the
whole population becomes antibiotic resistant.
