Racial Variations in Skin Color are Determined By

Question

Racial variations in skin color are determined by:
A) the number of melanocytes
B) the amount and type of melanin produced
C) the distribution and deposition of melanin
D) all of the these
E) the amount and type of melanin produced and the distribution and deposition of melanin

Accepted Answer

Racial variations in skin color are determined by both the amount and type of melanin produced as well as the distribution and deposition of melanin. Different amounts and types of melanin are produced by melanocytes in response to different stimuli such as UV radiation, hormones, and genetics. The distribution and deposition of melanin within the skin also affects skin color, as melanin can be concentrated near the surface or spread throughout the layers of skin. Therefore, both factors play a role in determining skin color differences between individuals of different races.
