Answer:
"African Americans predominantly carry a strong hereditary risk factor for sickle cell disease."

This disease is characterized by a change in red blood cells, which lose their round and elastic shape, acquire the appearance of a sickle (hence the name sickle cell) and harden, which makes it difficult for blood to pass through small vessels and oxygenate the blood vessels. fabrics.
After statistical research, it was confirmed that this disease originates in the African continent, which explains the hereditary risk factor that African Americans have in relation to this disease.
