Carriers are particularly significant in recessive genetic disorders. For a child to be affected by a recessive disorder, they must inherit two copies of the mutated gene, one from each parent. If both parents are carriers, there is a 25% chance with each pregnancy that the child will inherit both mutated genes and thus have the disorder. Common examples of recessive disorders include Cystic Fibrosis, Sickle Cell Anemia, and Tay-Sachs Disease.
