Detailed explanation-1: -Types of Mutations There are three types of DNA Mutations: base substitutions, deletions and insertions.
Detailed explanation-2: -Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection. Germline mutations (that occur in eggs and sperm) can be passed on to offspring, while somatic mutations (that occur in body cells) are not passed on.
Detailed explanation-3: -Genetic mutations are changes to your DNA sequence that happen during cell division when your cells make copies of themselves. Your DNA tells your body how to form and function. Genetic mutations could lead to genetic conditions like cancer, or they could help humans better adapt to their environment over time.
Detailed explanation-4: -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. They affect only some cells.
