A child inherits the sickle cell anemia train when he was a single gene for this disease and the parents, no signs of illness. However, if a child inherits genes from both parents and develop sickle cell anemia, which is much worse. Most of these children who have no access to medical care, and many die before they are old enough to have children themselves.
This cell is not just like a sickle. The allele for the sickle cell anemia and normal hemoglobin codominant. People who are heterozygous, have a normal hemoglobin allele and sickle cell anemia allele. You have a disease called sickle cell anemia, while those with two alleles of the sickle cell anemia, sickle cell anemia.
Heterozygous individuals have both normal hemoglobin and hemoglobin that causes sickle cell anemia.
