Content: Hereditary mutations occur when there is an alteration in the cells that produce the egg or the sperm. These alterations are called germline mutations and can be passed from parent to child. If the germline mutation is inherited every cell in their child’s body will have the same error in the DNA sequence. That is how hereditary disease and illness are passed on. Other genetic mutations occur due to damage caused to the DNA sequences by lifestyle or environmental factors. Our cells have built in mechanisms that catch and repair most of the changes that occur during DNA replication or from environmental damage. As we age, however, our DNA repair does not work as effectively and we accumulate changes in our DNA. Related Article
