Question

The disorder in which the body cannot produce melanin is a type of:

• A. Polygenic disorder
• B. Chromosomal abnormality
• C. Monogenic disorder
• D. (a) and (b) above.

Answer 1

The correct option is C Monogenic disorder

• Albinism is a monogenic disorder arising due to mutation in a single gene responsible for producing melanin.
• Hence, melanin production doesn't take place. As a result, skin is pale and hair are white. Eyes are usually pink due to the absence of this pigment in retina and sclera.
