Zoology - Principles of Inheritance and Variation Question with Solution | TestHub

A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses. Germline mutations occur in the eggs and sperm and can be passed on to offspring, while somatic mutations occur in body cells and are not passed on. Mutation cannot be predicted as it depends on several factors.
