If both mother and father carry the gene, there's a 1 in 4 threat that their toddler may have albinism and a 1 in 2 threat that their infant may be a service. carriers don't have albinism but can pass at the defective gene.
X-linked inheritance
a few varieties of OA are exceeded on in an X-related inheritance pattern. This pattern influences boys and ladies differently: women who inherit the faulty gene emerge as carriers and boys who inherit the defective gene will get albinism.
when a mother is a service of an X-linked type of albinism, every of her daughters has a 1 in 2 hazard of turning into a service and each of her sons has a 1 in 2 risk of getting albinism.
