Solution

The correct option is D Autosomes
Sickle cell disease is inherited in an autosomal recessive pattern. This means that a child will not inherit the disease unless both parents pass down a defective copy of the gene. It is the blood-related disease where haemoglobin structure is distorted from spherical to sickle-shaped. This distorted shape has less affinity to bind with oxygen and thus cause anaemia.
