  • leucism

    Condition in which all types of skin pigment are reduced due to defects in pigment cell differentiation with the normal result a partially (often referred to as 'pied' or 'piebald'), or more rarely, completely white animal. Differs from albinism, which is caused by a lack of melanin only, in several ways, with one of the most apparent being that albino animals typically have red eyes whereas leucism does not normally affect eye colour. Pronounced, and sometimes spelled, leukism.
