Heredity can affect health because some genetic errors and changes may be linked to the mother's or father's genes that will be passed on to the child.
Explanation:
Everyone has two copies of each gene, one from the father and one from the mother. Most people are born with two normal copies of each gene. However, often the genes of either the father or the mother can contain changes and errors that represent diseases, or syndromes that will be passed on to their children. This can influence their health.
Individuals with inherited genetic disorders have a 50% chance of passing the mutation on to their children. These changes can increase the risk of cancer, syndromes and several other problems.
