GENERAL KNOWLEDGE

Detailed explanation-1: -If a parent carries a gene mutation in their egg or sperm, it can pass to their child. 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.

Detailed explanation-2: -Mutation is a sudden inheritable change that occurs in the sequence of the nitrogenous base pairs in the DNA. These mutations could be beneficial, harmful or neutral to the organism. Q. The sudden heritable genetic changes in an organism are called mutation.

Detailed explanation-3: -Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. There are also nonhereditary mutations that occur in cells outside of the germ line, which are called somatic mutations.
