Leucism is often used to describe the phenotype that results from defects in pigment cell differentiation and/or migration from the neural crest to skin, hair, or feathers during development.

The meaning of LEUCISM is an abnormal condition of reduced pigmentation affecting various animals (such as birds, mammals, and reptiles) that is marked by overall pale color or patches of reduced coloring and is caused by a genetic mutation which inhibits melanin and other pigments from being deposited in feathers, hair, or skin.

Le leucisme ou leucistisme est une mutation génétique qui empêche la production le dépôt normal de mélanine et d’autres pigments dans le plumage. Il existe deux principales formes de leucisme : pâleur généralisée due à une diminution équivalente de pigments dans toutes les plumes et présence de taches blanches causée par l ...

Jan 26, 2016 · Leucism is only a partial loss of pigmentation, which can make the animal have white or patchily colored skin, hair, or feathers. However, the pigment cells in the eyes are not affected by the condition. These are two very different conditions.

Leucisme is een afwijking bij dieren en mensen die leidt tot een verminderde pigmentatie. Leucisme lijkt op albinisme en wordt daar soms mee verward. Leucisme resulteert in een vermindering van alle types huidpigment, niet slechts van melanine .

Aug 19, 2024 · (zoology, pathology) An animal condition in which there is partial loss of pigmentation resulting in white, pale, or patchy coloration of the skin, hair, feathers, scales or cuticle, but not the eyes (caused by a reduction in multiple types of pigment, not just melanin).
