  5. __________ Sickle cell anemia is a blood disease that occurs among some people of African heritage. People with double recessive genes for sickle cell (cc) have the disease and suffer from a number of complications including kidney problems and they tend to die young. People with one dominant gene and one recessive gene (Cc) are carriers of the condition. Both double recessive and carriers are resistant to malaria, a deadly disease carried by mosquitoes in Africa. Double dominant people (CC) do not carry the disease and are otherwise healthy. They have no resistance to malaria, however, and they die at young ages from malaria. Thus both double dominants and double recessives tend to die young, the former from malaria and the later from sickle cell anemia. Mate a Cc "survivor" father with a Cc "survivor" mother.
