In humans, oculocutaneous (OCA) albinism is a collection of autosomal recessive disorders characterized by an absence of the pigment melanin in skin, hair, and eyes. That is, normal pigmentation ( A ) is dominant over albino characteristics.
For this question, assume the phenotype is determined by a single gene with two alleles. If two people have normal pigmentation, what possible phenotypes may be observed in their offspring?

The offspring may have: normal pigmentation or may have albinism.

Explanation:

In case 1:

AA  x  AA

will produce all offsprings with  genotype AA; normal pigmentation.

In case 2:

AA  x  Aa

has 50% chance of producing offsprings with genotype Aa and 50% chance of producing offsprings with genotype AA. Phenotype of offsprings in both cases will be normal.

In case 3,

Aa x Aa

has 25% chance of producing offsprings with genotype AA, 50 % chance of producing offsprings with genotype Aa and 25% chance of producing aa genotype.

Offspring with genotype AA or Aa will have normal pigmentation and offsprings with genotype aa will be albino.
