What if Sickle cell anemia is a disease passed by autosomal recessive inheritance.what is the likelihood that a person who has two parents with the disease will be a carrier or the defective gene?

If sickle cell anemia is inherited in an autosomal recessive manner, a person with two parents who both have the disease will inherit two copies of the defective gene. Consequently, this individual cannot be a carrier; they will be affected by the disease. In this case, the likelihood of being a carrier is 0%, as they will have the genotype that expresses the disease rather than one that carries it without symptoms.
