Both cases represent the superiority of the heterozygote, the homozygote gets the disease with its full power and dies, while the heterozygous is only affected halfway through all its cells, and can therefore, survive rather easily.

The shape of the cells. The curvature of sickle cells keep the virus of Malaria from being able to attach to the cell of the sickle cells.

People heterozygous for sickle cell trait are resistant to the plasamodium parasite that attacks red blood cells. The blood cell crenelates ( crinkles ), denying the parasites entrance into the cell. Naturally, homo zygotes, get the sickle cell disease.

actually sickle cell anemia is a genetic disease, about 1/4 of offspring get it. actually having sickle cell anemia doesn't protect you from malaria, being a carrier of the disease DOES protect you. being a carrier of sickle cell anemia, you have a change in ONE amino acid on your RBC (red blood cell), which protects you from malaria. but actually having sickle cell anemia your RBC's will be curved, in a sickle shape, and it will be difficult for them to travel through your capillaries and deliver oxygen and nutrients to your tissues.

Sickled blood cells make it difficult for malaria viruses inject their offspring into them. Therefore virus reproduction is inhibited.
