A person that has only one mutated gene and one normal gene remains healthy but is a **carrier**, thus able to pass on the disorder to their children.


 * If both parents of a child are carriers:**
 * There is a 25% chance that the child will have sickle cell anemia.
 * There is a 25% chance that the child will not carry any mutated genes at all.
 * There is a 50% chance that the child will be a carrier.




 * If one parent has sickle cell anemia while the other parent is normal:**
 * All of their children will be carriers.




 * If one parent has sickle cell anemia while the other parent is a carrier:**
 * There is a 50% chance that a child would have sickle cell anemia.
