Description- reaping hook-cell genus Anemia is a he cherry-redity race disease. Those who call for sickle-cell anemia have red linage cells containing an ab blueprint type of hemoglobin called haemoglobin S. A normal persons red blood cells have Hemoglobin A, and are round and soft which makes it easy for them to tie through the small blood vessels. The lifespan of a normal blood cell is approximately 120 days. But those with sickle-cell anemia lack normal hemoglobin, and their lifespan is only 16 days. Hemoglobin is the substance that makes blood red and that carries oxygen to the body tissues. In this case the amount of oxygen, in the blood, is reduced for no reason. Sickle hemoglobin forms a type of crystallisation in the red blood cell. When the cell loses oxygen as it goes through capillaries, the crystal then causes the normal round red blood cells to revision into slender, twisted, rigid sickle forms. Sickle cells stick to ingesther and get trapped in the capillaries and block the normal flow of blood through them. When sickle-shaped cells plug up small blood vessels, lesser blood reaches various parts of the body. This damages the tissue, which does not receive normal blood flow. This is what causes the complications of sickle cell disease.
        preponderating? Recessive? - Sickle cell is recessive.
In order for a newborn to posses this character they have to receive one sickle hemoglobin, component, from each parent. If the child gets only one copy of the gene form one parent then the child has sickle-cell trait but do not have the disease.
Chromosome- Sickle-cell anemia is placed on chromosome 11.
What Ethnicity? - In the United States sickle cell occurs super in African Americans. It also affects other groups, including Hispanics, Middle Eastern, and Mediterranean ancestry. It also occurs among the people of India,
