Answer 1

Albinism is a inherited disorder characterized by lack of melanin in skin,hair and eye

Step-by-step explanation:

Two parents with normal pigmentation have an albino child.

• There is a one-in-four chance that their next child will have albinism, a two-in-four chance that he or she will be a carrier .
