Did You Know?

An aberration occurring in humans and other vertebrates, albinism is an absence of pigment in the eyes, skin, hair, scales, or feathers caused by a genetic defect. Albino animals rarely survive in the wild because they lack the pigments that normally provide the protective coloration and a screen against the sun’s rays. Humans have long bred certain albino animals, such as rabbits, for their appearance. In humans with total albinism, the affected person has milk-white skin and hair; the iris of the eye appears pink and the pupil is red. Problems with vision are common in albinism. Total albinism occurs in all races in about one in 20,000 persons.
