Solution

The correct option is A [A] is true and [R] is false

Albinism is a genetic disorder arising due to the mutation in the gene responsible for production of melanin. Due to which, melanin production doesn't take place.

It is a genetically inherited recessive trait. This means that an albino couple would produce only albino children.

Due to the absence of melanin, skin is pale and hair are white. Eyes are usually pink due to the absence of pigment in retina and sclera.
