Question 1 Report

Which of the following diseases is transmittable through genes?
Answer Details
Sickle cell anemia is the disease that is transmittable through genes. It is a genetic disorder caused by a mutation in the hemoglobin gene. People with sickle cell anemia inherit two copies of the mutated gene, one from each parent, and this causes the hemoglobin in their red blood cells to be abnormal. The abnormal hemoglobin causes the red blood cells to take a crescent or sickle shape, which can block blood flow, leading to pain, organ damage, and an increased risk of infections.
