For most types of OCA, both parents must carry an albinism gene to have a child with albinism. Parents may have normal pigmentation but still carry the gene. When both parents carry the gene, and neither parent has albinism, there is a 25% chance at each pregnancy that the baby will be born with albinism.Autosomal recessive inheritance
This means a child has to get 2 copies of the gene that causes albinism (1 from each parent) to have the condition. If both parents carry the gene, there’s a 1 in 4 chance that their child will have albinism and a 1 in 2 chance that their child will be a carrier.It all depends on whether you AND your wife carry an albinism gene. If the two of you do, then each child has a 1 in 4 chance of having albinism. If only one or neither of you is a carrier, then each child has pretty close to a zero chance for albinism. To end up with albinism you need to inherit it from both parents.
What happens when 2 albinos have a baby?

Can 2 parents with albinism have an unaffected child?
Since the parents are both affected by albinism, then their children will not be able to inherit the dominant allele for it to be unaffected by the disease. Therefore, we conclude that getting an unaffected child from two parents with albinism is impossible.
Can human albinos reproduce?
The chance of offspring with albinism resulting from the pairing of an organism with albinism and one without albinism is low. However, because organisms (including humans) can be carriers of genes for albinism without exhibiting any traits, albinistic offspring can be produced by two non-albinistic parents.
How long is the average lifespan of a person with albinism?
Albinism is not associated with mortality. Lifespan is within normal limits. Because the reduction of melanin in the hair, skin, and eyes should have no systemic effects, the general health of a child and an adult with albinism is normal.
What race is albinism most common in?
OCA 2 is the most common type of albinism and is especially frequent among African Americans and Africans. The estimated frequency in African Americans is 1 case per 10,000 population, while in whites, the frequency is 1 case per 36,000 population. The overall frequency is 1 case per 15,000 population across all races.
Can 2 albinos have a non albino baby?
For most types of OCA, both parents must carry an albinism gene to have a child with albinism. Parents may have normal pigmentation but still carry the gene. When both parents carry the gene, and neither parent has albinism, there is a 25% chance at each pregnancy that the baby will be born with albinism.
