Question

Quizplus · Accepted Answer

Mutation is the most prolific source of genetic variation in living organisms as it is responsible for introducing new alleles and gene variants into a population. Mutations can occur spontaneously or can be induced by exposure to mutagens, such as radiation or chemicals. Mitosis, transcription, and translation are all important cellular processes but do not introduce new genetic variation. Viral insertion can introduce new genetic material into a host organism's genome but is not as common or widespread as mutations.
