The albinism gene is recessive and hence does not cause albinism unless a person inherits two copies of the gene for albinism in other words if there is no gene that makes the normal pigment.
If a person has one gene for normal pigmentation and one gene for albinism, he or she will have enough genetic information to make normal pigment and will not suffer from the disease.
When both parents carry the gene and neither of them have albinism (carriers), then there is 25% chance that the baby will be born with albinism. This type of inheritance is called autosomal recessive inheritance. On the other hand two people with albinism will not automatically produce an albino child although the risks are several times higher. Therefore in conclusion researchers say that the disease is a mystery and more research has to be done in this area to completely understand it.
