do white peolpe have melanin in theirskin
More melanin presence in the skin makes the skin appear black, and less melanin will make the skin appear less black. White people have very little melanin synthesized by their skin. So, the color of the races is because of some difference in the quanitity of the melanin pigment in our body. That is all.
Skin color is due primarily to the presence of a pigment called melanin, which is controlled by at least 6 genes. Both light and dark complexioned people have melanin. However, two forms are produced--pheomelanin, which is red to yellow in color, and eumelanin, which is dark brown to black.
