Detailed explanation-1: -There are many genetic tests that require a sample of your blood, skin, hair, amniotic fluid or tissues to identify changes to your genes, chromosomes or proteins. Genetic testing can locate mutated genes or chromosomes that cause genetic conditions.

Detailed explanation-2: -Mutations can be of many types, such as substitution, deletion, insertion, and translocation.

Detailed explanation-3: -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.
