1. Furthermore, the effects on eumelanin and pheomelanin are not equal. 2. Two types of pigment give hair its color : eumelanin and pheomelanin. 3. Melanosomes containing eumelanin are eumelanosomes, while those containing phaeomelanin are phaeomelanosomes. 4. There are three basic types of melanin : eumelanin , pheomelanin, and neuromelanin. 5. Such phenotypes result mostly from single mutations associated with an increase of eumelanin deposition. 6. A small amount of black eumelanin in the absence of other pigments causes grey hair. 7. In addition to eumelanin , melanocytes can generate a yellow / red pigment called phaeomelanin. 8. Many, many animals have eumelanin in their melanocytes or melanophores in skin and scales. 9. Dopaquinone may become eumelanin , or phaeomelanin. 10. Darkly pigmented, eumelanin -rich skin protects against DNA damage caused by the sunlight.
