People with only one abnormal gene in the gene pair are called carriers, but since the gene is recessive they do not exhibit the disease. In other words, the normal gene of the pair can supply the function of the gene so that the abnormal gene is described as acting in a recessive manner. BOTH parents must be carriers in order for a child to have symptoms of the disease. A child who inherits the gene from one parent will be a carrier.
