Some diseases are passed from parents to offspring through their genes, these are considered genetic diseases. Some of the inherited disorders that fall into this category include Tay-sachs disease, sickle-cell anemia, hemophilia, and cystic fibrosis. A child can suffer from one of these diseases only if both parents pass on a recessive gene for the disease. Cystic Fibrosis results in the body producing abnormally thick, sticky mucus which clogs the lungs leading to recurring infections.
