You are a Science enthusiast, and are currently interested in studying the concept behind various kinds of complexion in the world population. You consider three individuals in a group, who have the typical looks of an African negro, an Indian, and a European. Arrange them in increasing order of the amount of melanin in their skin.
European, Indian, African
Melanin is a pigment contained in the malpighian layer of the epidermis of the skin. It is responsible for skin colour/complexion. Greater the amount of melanin in the skin cells, darker would be the colour of the skin, and vice versa. Hence, among the individuals in the given group, the European would have least amount of melanin in the skin, followed by the Indian and finally, the African negro.
