Inheritance of skin colour in man is

A.
Monogenic
B.
Bigenic
C.
Trigenic
Answer
D.
Polygenic

Answer: Option C

Solution

Answer: Option C
Solution:
Inheritance of skin colour in man is Trigenic.
Human skin color ranges from the darkest brown to the lightest hues. The genetic mechanism behind human skin color is mainly regulated by the enzyme tyrosinase, which creates the color of the skin, eyes, and hair shades.
Skin colour inheritance in man is controlled by multiple genes and hence it is an example of polygenic inheritance.
