Answer & explanation
Correct answer: option 2
The correct answer is Option (2)-Mutation
Mutation is a sudden, stable and inheritable change in genetic material or DNA sequences of an organism. The organism, which undergoes mutation is called mutant. The chemical and physical factors that induce mutations are called mutagens, e.g. UV radiations, etc. Mutation occurring due to change in a single base pair of DNA. This is called point mutation, e.g. sickle-cell anaemia. Deletions and insertions of base pairs of DNA cause frameshift mutation
