Final answer:
Albinism is an autosomal recessive disorder that results in the lack of pigmentation. A normally pigmented man with an albino uncle suggests the presence of albinism in the family, indicating possible carrier status for the man, as he has normal pigmentation.
Step-by-step explanation:
Albinism is an autosomal recessive disorder, meaning that the trait for albinism is only expressed when an individual has two copies of the recessive allele, one from each parent. In the case presented, a normally pigmented man with an albino uncle implies a family history of albinism. Since albinism is recessive, the man's parents were likely not affected but possibly carriers of the trait if the uncle is a full sibling to one of the parents.
It is not uncommon that carriers of an autosomal recessive disorder like albinism are phenotypically normal but can still pass the gene to their offspring, which may result in a child with albinism if the other parent is also a carrier or has albinism. Given that the man's uncle has albinism, the man's phenotype for normal pigmentation indicates that he has at least one dominant allele but might carry the recessive allele responsible for albinism.
