Albinism is the congenital absence of any pigmentation or colouration in an animal, plant, or person, resulting in white hair, feathers, scales and skin and pink eyes in mammals, birds, reptiles, amphibians and fish and invertebrates as well.

What are people without pigment called?
The term albinism typically refers to oculocutaneous (ok-u-low-ku-TAY-nee-us) albinism (OCA) — a group of inherited disorders where there is little or no production of the pigment melanin. The type and amount of melanin your body produces determines the color of your skin, hair and eyes.
What is Leucism?
: 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.
Can humans have Leucism?
Therefore, leucistic phenotypes can be associated with defects, which mainly impair sensory organs and nerves. In humans, a well-known example is the Waardenburg syndrome. Leucism-associated disorders were also described in mouse, rat, hamster, rabbit, mink, cat, dog, pig, sheep, llama, alpaca, cattle and horse.
Is Leucism the same as albinism?
Albinism is a condition in which there is an absence of melanin. Melanin is what is present in the skin and is what gives skin, feathers, hair and eyes their color. ... Leucism is only a partial loss of pigmentation, which can make the animal have white or patchily colored skin, hair, or feathers.
What is an albino person?
What is albinism? Albinism is a rare genetic disorder where you aren't born with the usual amount of melanin pigment. Melanin is a chemical in your body that determines the color of your skin, hair and eyes. Most people with albinism have very pale skin, hair and eyes. They are prone to sunburn and skin cancer.
What is it called when an animal is all black?
Melanism is an undue development of dark-colored pigment in the skin or its appendages and is the opposite of albinism. The word 'melanism' is deduced from a Greek word that means black pigment. ... Below you will find a fascinating gallery of ten melanistic (all black) animals.
What is a leucistic Magpie?
All the snowy white magpies in this tribe have leucism — a rare genetic mutation which scrambles pigment codes during embryonic development. Leucism is more common in magpies than other species, according BirdlLife Australia's Sean Dooley, because smaller birds with the mutation tend not to last long.
What is a leucistic Cardinal?
A fully leucistic Cardinal lacking all melanin in all feathers. ... These birds can produce melanin, so the eye appears black, but something prevents them from depositing melanin in the growing feathers. The red carotenoid pigment is unaffected so the feathers are red in all the normal places for a female cardinal.
What is a leucistic blackbird?
Leucistic Blackbird
Some birds suffer from a similar condition called dilution in which the plumage colour appears “washed out”. Melanin cells are present but they produce less pigment than normal.
What is a leucistic squirrel?
There are two basic types of white squirrels: albino and leucistic. Albinos have pink or blue eyes and no dark pigments anywhere on their bodies. Squirrels that have white coats and dark eyes are called leucistic. ... They argue that hawks and other wild predators may not recognize a white squirrel as food.
What is the difference between leucistic and Piebald?
Birds that show only white patches or sections of leucistic feathers, often in symmetrical patterns, are often called pied or piebald birds, while birds with fully white plumage are referred to as leucistic birds.
Is melanism rarer than albinism?
Nothing illustrates this sentiment better than melanism — a rare genetic mutation — even more uncommon than albinism — that turns animals pitch-black, truly making them a sight to behold.
Can any animal be leucistic?
Like albinism, leucism can present as a fully white animal (however, with black eyes). But it can also present as a paler-colored, but not white, animal, or a 'pied' animal (normally colored with white or pale splotches throughout the body).
