Detailed explanation-1: -A population of bacteria is treated with hand sanitizer. Because a genetic variation in the population, what is a possible outcome? All of the bacteria are already resistant.

Detailed explanation-2: -Genetic variation describes naturally occurring genetic differences among individuals of the same species. This variation permits flexibility and survival of a population in the face of changing environmental circumstances.

Detailed explanation-3: -The genetic diversity has three different sources: mutation, recombination and immigration of genes.

Detailed explanation-4: -Prokaryotic cells have developed a number of methods for recombining their genetic material, which, in turn, contributes to their genetic diversity. The three most common ways that bacteria diversify their DNA are transformation, conjugation, and transduction.

Detailed explanation-5: -According to Charles Darwin’s theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
