Hemoglobin
It is Hemoglobin
Sickle Cell disease A disease that involves misshaped cells that can easily cause blood clots.
People who are heterozygous for sickle cell disease possess one normal hemoglobin gene and one sickle hemoglobin gene, which allows them to produce enough normal red blood cells to prevent symptoms of the disease. This condition, known as sickle cell trait, provides some protection against malaria, as the presence of sickle hemoglobin can interfere with the parasite's life cycle within red blood cells.

Sickle cell disease is an inherited blood disorder that affects red blood cells.
It's not sickle-cell itself, but rather being a heterozygous carrier of the disease. People with one dominant and one recessive allele for the disease are immune to malaria without the crippling effects of having sickle-cell anemia. I don't think that it can even represent codominance, though.
sicklers are as any normal person so they can get seizure not because sickle cell disease , but because any other disease
sickle cell disease
million people have sickle cell world wide i think
The defect is that hemoglobin (the protein) elongates. Instead of being circular, it acquires a crescent shape. With this shape, its harder for it to absorb and release oxygen. Also, when the blood cell reaches the capillaries, it can't fit through as well as normal blood cells can, which is why Sickle-Cell is painful.

There are several types of sickle cell disease, including sickle cell anemia, sickle beta thalassemia, and sickle cell-hemoglobin C disease. These types differ based on the specific genetic mutations that affect the hemoglobin protein in red blood cells. Sickle cell anemia is the most common and severe form, where individuals have two copies of the sickle cell gene. Sickle beta thalassemia and sickle cell-hemoglobin C disease are milder forms that result from different combinations of genetic mutations. Symptoms and complications can vary among the different types of sickle cell disease.
