albinism is due to the inability to make
Albinism Albinism results from inheritance of recessive gene alleles and is known to affect all vertebrates, including humans. It is due to absence or defect of tyrosinase, a copper-containing enzyme involved in the production of melanin. It is the opposite of melanism. Unlike humans, other animals have multiple pigments and for these, albinism is considered to be a hereditary condition characterised by the absence of melanin in particular, in the eyes, skin, hair, scales, feathers or cuticle.[4] While an organism with complete absence of melanin is called an albino an organism with only a diminished amount of melanin is described as leucistic or albinoid.[5] The term is from the Latin albus, "white".
