Detailed explanation-1: -DNA mutations in somatic cells can affect an individual, but they cannot be passed on to their offspring.
Detailed explanation-2: -An alteration in DNA that occurs after conception. Somatic mutations can occur in any of the cells of the body except the germ cells (sperm and egg) and therefore are not passed on to children.
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: -The sperm and egg pass from parents to their children, so the mutation is inherited. You can’t inherit somatic mutations because they occur randomly in cells that aren’t the sperm or egg.
Detailed explanation-5: -Somatic mutations are a normal part of aging and occur throughout an organism’s life cycle either spontaneously as a result of errors in DNA repair mechanisms or a direct response to stress. Mutations occurring early in development can cause mosaicism within the gene line, impacting organism development.
