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 albinism (a). For this question, assume it is a single gene with two alleles. Assume it is a single gene with two alleles. If two people have normal pigmentation, what possible phenotypes may be observed in their offspring?

Answer:

The definition of the problem is listed in the explanation segment below.

Explanation:

  • The parent phenotype is an albino on every one of them. Albino gene seems to be located primarily while it has its whole genotypes in such a recessive state called "aa".  
  • When this trait becomes autosomal, it does have an equivalent amount of alleles across both parent members. The gametes including its albino genotypes.

        ⇒  [tex]Mother \ aa\times Father \ aa[/tex]

        ⇒  [tex]a\times a[/tex]

  • Genotype including its offspring - albino.
  • Well, all offspring will also have albino phenotypes.

So that the above is the right answer.
