The environment plays an important role in the determination of the phenotype of the organisms. Some traits are controlled by the environmental as well as by the genetic factors.

The skin color is an example of polygenic trait in which more than two genes are involved for the phenotype of an individual. The individual have their fixed DNA for the skin color. The individual's DNA responsible for the skin color gets change over time due to the evolution and according to the environmental factors as well. The uneven geographical distribution and temperature influence has caused more variation in the skin color.
