Explanation: 

Detailed explanation-1: -The term albinism usually refers to oculocutaneous (ok-u-low-ku-TAY-nee-us) albinism (OCA). OCA is a group of disorders passed down in families where the body makes little or none of a substance called melanin. The type and amount of melanin in your body determines the color of your skin, hair and eyes.

Detailed explanation-2: -This phenomenon is known as leucism, the partial loss of all types of pigmentation, including carotenoids. Leucism causes white coloration, white patches, spots, or splotches on the skin or fur. Leucism is also discernible from albinism because leucism does not affect the pigment cells in the eyes.

Detailed explanation-3: -Both of the parents of the offspring must carry the gene in order for the animal to be albino. Some animals are full albino while others possess albino traits. Partial albinism is known as leucism. Animals that are leucistic might have white fur, scales, or skin but their eyes will not be pink or red.

Detailed explanation-4: -Some species, such as white peacocks, swans and geese, are not believed to be true albinos, as they do not have red eyes, rather, their colouration is suggested to be the expression of a white fur or feather gene, not a lack of melanin.
