A single-gene trait is one in which the expression is determined by the input of two alleles for the gene. One allele for the single-gene trait is inherited randomly from father's two alleles and one is inherited randomly from the mother's two alleles for that same single-gene trait. A person with the normal number of chromosomes only inherits two alleles (one from each parent) regardless of how many possible alleles are present in the human population for this single-gene trait.
