If this DNA has a mutation, the child that grows from the fertilized egg will have the mutation in each of his or her cells. Acquired (or somatic) mutations occur at some time during a personâs life and are present only in certain cells, not in every cell in the body.
Best Answer: Most mutations are harmful, and most organisms that get these mutations are never even born (hatched or sprouted). If an organism with a harmful mutation does survive, it usually doesn't do as well as its normal relatives. For example, in humans, Downs' Syndrome is a mutation where the person gets an extra chromosome #23.
