Sickle Cell Anemia
Sickle cell anemia is a group of blood disorders that develop when a person inherits a specific recessive gene mutation. Gene mutations are permanent changes in a genetic sequence. The sickle
cell mutation affects the structure of hemoglobin; hemoglobin allows red blood cells to carry oxygen. In order for a person to have sickle cell anemia, they have to inherit two copies of the recessive
allele, one from each parent. The diagram shows the genotypes of an unaffected person and a person with sickle cell anemia.
