Albinism is a recessive trait. A man and woman who both have normal pigmentation have one child out of three who has albinism (without melanin pigmentation). The genotypes of this child's parents: (C) Both parents must be heterozygous.
Albinism is an autosomal and not a sex-linked recessive trait.
Only homozygous recessive (aa) offspring will be albino, both homozygous dominant (AA) and heterozygous dominant (Aa) offspring will possess the normal phenotype.
Since it is given that both the father and the mother have normal pigmentation, thus they must both have the genotype Aa.
From the Punnett square it can be observed that a cross between the parents would result in the creation of three offspring with the normal genotype (one with AA and two with Aa) and one offspring with the genotype aa (albino).
