"Albinism is an inherited genetic condition that reduces the amount of melanin pigment formed in the skin, hair and/or eyes…Most children with albinism are born to parents who have normal hair and eye color for their ethnic backgrounds…A common myth is that people with albinism have red eyes. In order for your children to express albinism, both parents must be carriers of the OCA gene. both are normally pigmented, but each has one albino parent. What are the genotypes of these three persons? The woman and the first child are homozygous recessive (nn). Albinism causes a person. If both parents are normally pigmented, that is, neither one of them has albinism, but they both happen to be carriers of the recessive "albinism" gene. The oval shaped, milchkaffeefarbenen patches (Café au-lait spots) and the summer shoots-like Sprenkelungen in the armpits and the groin area show around 80 percent of diseased infants in the first year of life. If their first child is born with the disease, we know that John and Carol's genotype must be Aa and they are both carriers. One of the parents was homozygous for albinism. Consequently, the albino has a high incidence of sunburns, elastosis, actinic keratosis (pre-malignant) and skin cancer.
