     The genes for this disorder are located on the autosomal chromosomes. We normally have two copies of the chromosomes and the genes on them, but neither of them is functional in people with albinism. Albinism is a recessive trait, so even if only one of the two copies is functional, a person can make pigment, but will carry the albinism trait. Both parents must carry a defective gene to have a child with albinism. When both parents carry the defective gene there is a one in four chance at each pregnancy that the baby will be born with albinism. This type of inheritance is called autosomal recessive.^[1]
