Albinism
Disorder causing lack of pigmentation
Albinism is the congenital absence of pigmentation (in mammals, melanin) in an animal or plant resulting in "hair being white, red, or yellow", "feathers, scales, and skin being yellow", "eyes being red, pink, purple, violet, or blue", and "leaves or stems being white or yellow", if applicable. Individuals with the condition are referred to as albinos. Varied use and interpretation of the terms mean that written reports of albinistic animals can be difficult to verify.
