English: Albinism (from Latin albus, meaning "white") is a lack of melanin pigmentation in the eyes, skin and hair. It is an inherited condition resulting from the combination of recessive genes passed from both parents of an individual. This condition is known to affect mammals, fish, birds, reptiles, and amphibians.
Deutsch: Albinismus (lat. albus = weiß) ist eine Sammelbezeichnung für angeborene Störungen in der Biosynthese der Melanine und dem daraus resultierenden Mangel an Pigmenten in Haut, Haaren und Augen (Rotfärbung der Iris aufgrund des durchschimmerndes Blutes). Teilweiser Albinismus äußert sich in aufgehellter Farbe.
Français : Albinisme (du latin albus, qui signifie blanc) se traduit par une absence de pigmentation des yeux, de la peau et des poils. C'est un facteur héréditaire dues à la combinaison de gènes récessifs provenant des deux parents. L'albinisme est connu chez les mammifères, les poissons, les oiseaux, les reptiles et les amphibiens. Une absence partielle de la pigmentation donnera des individus dont les yeux seuls sont privés de mélanine, ou seulement quelques parties du corps (voir animaux colorpoint). On ne doit pas confondre avec le leucitisme, coloration plus claire que la normale, parfois presque blanc, mais qui n'affecte pas les yeux.
Português: Albinismo (do latim albus, que significa branco) é uma deficiência de melanina nos olhos, pele e cabelo. Essa doença é uma condição hereditária, resultada da combinação de genes recessivos passados por ambos os pais ou por apenas um dos dois. É conhecida por afetar mamíferos, peixes, aves, répteis e anfíbios.
Español: Albinismo (del latín albus, que significa 'blanco') es la carencia de melanina en los ojos, la piel y el pelo. Es una condición hereditaria que resulta de la combinación de genes recesivos que son pasados por los dos padres de un individuo. Se sabe que esta condición afecta a los mamíferos, peces, aves, reptiles y anfibios.

Abnormal melanocyte migration

Leucism: Melanocytes fail to migrate normally from the neural crest partially (white markings, spotting, roaning) or totally (all-white animal). Any sites with migrated melanocytes produces pigments normally unless additionally affected by albinism. Microscope findings of leucistic sites will show no traces of pigments.
Leucistic white: An all-white animal, as distinguished from albino-white or partially leucistic animals.

Abnormally low intensity of pigments

Albinism: Lowered intensity of melanin pigments in normally migrated melanocytes.
Albino: Such a low intensity of melanin pigments that the individual appears white, usually with red or light grey/blue eyes. Non-mammalian albinos may form other pigments normally.
Dilution: Lowered intensity of pigment in normally migrated melanocytes.
Axanthism: in birds, reptiles, fish and amphibians: lack of red and yellow xanthin pigments.
Amelanism: lack of red and black melanin pigments.

Abnormal distribution of pigments

Erythrism: Abnormally intense or widespread red pigmentation (both erythrin and pheomelanin??).
Xanthism: Abnormally intense or widespread xanthin yellow pigmentation.
Melanism: Abnormally intense or widespread eumelanin black pigmentation.
