What is characteristic of an albino horse's hair?

An albino horse's hair is characterized by being milky colored and lacking pigment due to a genetic condition known as albinism. This condition prevents the production of melanin, the pigment responsible for color in hair, skin, and eyes. As a result, the hair appears white or very light, giving it a unique appearance that distinguishes it from horses with normal pigmentation. This lack of pigment extends to other parts of the horse's physiology, making them particularly sensitive to sunlight, as their skin does not produce the protective melanin that helps shield against UV rays. The milky color is a direct result of this genetic trait, making it the defining characteristic of an albino horse.
