Question

The colour of skin and hair is determined by

• A. Melanin
• B. Rhodopsin
• C. Bile
• D. Aqueous humour

Answer 1

The correct option is A Melanin

• Melanin is produced within the skin in cells called melanocytes and it is the main determinant of the skin colour of darker-skinned humans. The skin colour of people with light skin is determined mainly by the bluish-white connective tissue under the dermis and by the haemoglobin circulating in the veins of the dermis.
• Hair colour is determined by the amount of a pigment called melanin in hair. An abundance of one type of melanin, called eumelanin, gives people black or brown hair. An abundance of another pigment, called pheomelanin, gives people red hair. Hence, The colour of skin and hair is determined by Melanin.

So, the correct answer is 'melanin'.
