विकल्प

• Colour blindness

• Thalassemia

• Sickle cell anaemia

• Haemophilia

Answer 1

Sickle cell anaemia is an example of pleiotropy.

Explanation:

Pleiotropy refers to a single gene influencing multiple traits. Haemophilia is a metabolic illness characterised by uncontrollable bleeding from minor wounds due to a lack of clotting factors. It's a recessive gene that's passed down through the generations. Sickle cell anaemia is a hereditary condition produced by a recessive mutant gene that regulates haemoglobin structure, which is frequently fatal in bomozygotes. Thalassemia is a serious blood disorder that affects both men and women.
