Explanation:
Aplastic anaemia can be described as an autoimmune disorder in which the number of blood cells in the body is a lot lesser than the actual requirement of the body. It is a deficiency in all the blood cells of the patient's body.
Erythropoiesis is a process by which red blood cells are produced in the body of a person.
Hence, in a person suffering from aplastic anaemia, a decrease in the process of erythropoiesis will be observed.
