Detailed explanation-1: -Ionizing radiation damages the genetic material in reproductive cells and results in mutations that are transmitted from generation to generation.
Detailed explanation-2: -These hereditary (or inherited) mutations are in almost every cell of the person’s body throughout their life. Hereditary mutations include cystic fibrosis, hemophilia, and sickle cell disease. Other mutations can happen on their own during a person’s life. These are called sporadic, spontaneous, or new mutations.
Detailed explanation-3: -A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.
Detailed explanation-4: -The chemical or physical agents that cause mutations are called mutagens. Examples of physical mutagens are ultraviolet (UV) and gamma radiation.
