eumelanin

In the skin and eyes, only eumelanin is present.

Mc1r allows the black pigment eumelanin to form in hair.

It has large amounts of eumelanin and is less dense than other hair colors.

Eumelanin is the dominant form of melanin found in human skin.

Higher concentrations of the black pigment eumelanin can indicate cancer.

Furthermore, the effects on eumelanin and pheomelanin are not equal.

Eumelanin is typically black, but may instead be brown, dark gray, or light gray-brown.

The second (E) locus determines whether the eumelanin is produced at all.

Two types of pigment give hair its colour: eumelanin and pheomelanin.

The loss of eumelanin in the coat is, in these species, harmless.

Extension controls whether or not true black pigment (eumelanin) can be formed in the hair.

The pigment eumelanin gives brown hair its distinctive color.

This results in deposition of eumelanin into the hairs of the dog.

Two types of melanin, eumelanin and phaeomelanin, are present in birds.

Eumelanin determines the darkness of the hair color.

Hair contains a mixture of black-brown-yellow eumelanin and red pheomelanin.

Such phenotypes result mostly from single mutations associated with an increase of eumelanin deposition.

They say that cells make two different pigments - dark brown eumelanin and red/orange pheomelanin.

Eumelanin predominates in the legs, mane and tail of bay horses.

Eumelanin, which has two subtypes of black or brown, determines the darkness of the hair colour.

Red hair has the highest amounts of pheomelanin, around 67%, and usually low levels of eumelanin.

In some amphibian species there are other pigments packaged alongside eumelanin.

A small amount of black eumelanin in the absence of other pigments causes grey hair.

A dog that is recessive red cannot produce eumelanin (black) pigment in their fur.

People with naturally occurring dark skin have melanosomes which are clumped, large, and full of eumelanin.
