Sickle cell anemia is a disease caused by a mutation at the genotypic level. A person with two copies of the gene has the disease, but a person with one copy of the gene does not have the disease. The diagram shows how this mutation affects an organism.   Use the image to answer the question. The mutation causes the deformity of the red blood cell, the component of blood that carries oxygen throughout the body. The deformed cells can clump together and can clog blood vessels. The parasites responsible for the sickle cell condition are killed in the deformed red blood cells. In which type of environment would carriers of the disease be naturally selected for?   A. low altitude   B. high altitude   C. low population of parasites   D. high population of parasites

Hematology

Hematology is the branch of biology. Hematology is the medical field that deals with the treatment of blood disorders and cancers, such as hemophilia, leukemia, lymphoma, and sickle-cell anemia. Hematologists and hematopathologists are medical professionals who specialize in illnesses of the blood and its components.
