Animal Colour Mutations
Color Mutations: Albinism One of the most known and widely seen mutations in nature is albinism. Present at birth, albinos are characterized by the lack of the pigment melanin, which typically gives color to the eyes, skin, and hair. Albinism can be found in all species and races; in animals it usually displays as yellow or pink skin, and pink.
Rare genetic color mutations can make animals that are usually familiar to us look completely different. See Piebald, Erythristic, Chimeric animals, and more! Penguins are black and white. So are pandas.

Elephants are grey, and tigers are orange with black stripes. Everyone knows all this-in fact, for some people, it may be the only thing they know about those animals. And yet exceptions exist to every rule about the color of animals.
Every so often, a specimen gets a mutation that changes its whole appearance. The creature may stand as a weird. Leucistic animals have a mutation that reduces the amount of melanin and other pigments in their fur, feathers, or skin (but not eyes).

"Leucinos" may appear virtually pure white but still possess "normal-colored" eyes and skin; they may possess only a single white feather but otherwise appear normal; or they may exhibit partially white plumage. Genomic studies conducted to date depict a diverse spectrum of genetic architectures, including single coding mutations underlying colour variation between populations, alternative cis- regulatory changes controlling colour variation within and between species, and supergenes associated with discrete colour morphotypes, among others (figure 1. Discover 37 fascinating facts about color mutations in nature, animals, and plants.
Learn how these unique changes impact the world around us. In some cases, this is easily explained away. Some animals, particularly those in the arctic, change color in the winter to match the snowy landscape.
Animal Color Mutations
And some animals, namely the chameleon, are famous for their color-changing ability. Other times, though, a wrong-colored animal seems to defy explanation, or at the very least generate awe. Examples of color variations caused by mutations include albino, where animals have a lack of pigment, and melanistic, where animals have an excess of pigment.
In conclusion, understanding the inheritance patterns of pigment genes is key to comprehending color genetics in animals. Many associations between skin and coat color and developmental anomalies have been recorded in domestic animals. Some of the associations with hypotrichosis are discussed under hereditary alopecia.
Albinism appears to be rare in domestic animals. True albinism is always associated with pink or pale irises and with visual defects and increased risk of solar radiation. White tigers, black panthers, and other animals with unique color mutations are rare in the wild.
Additionally, the few born with color mutations may struggle to survive.
