Summary

The illustration shows how sickle cell genes are inherited. A person inherits two copies of the hemoglobin gene—one from each parent. A normal gene will produce normal hemoglobin (A). An abnormal (sickle cell) gene will produce abnormal hemoglobin (S). When each parent has a normal gene and an abnormal gene, each child has: a 25 percent chance of inheriting two normal genes; a 50 percent chance of inheriting one normal gene and one abnormal gene; and a 25 percent chance of inheriting two abnormal genes.
