What role do dna and environmental factors play in an organism's traits

DNA and Environment both plays an important role in an organisms trait.

Explanation:

There have an impact of environment on the phenotype. Environmental factors like-light, temperature, humidity all can effect the phenotype of an organism. when the organisms which are genetically identical, like mono zygotic twins, are exposed to different environment can show difference in their phenotype. DNA contains the genetics codes. These genetic codes are used to make proteins, which in turn help to determine the physical characteristics and biological functions of an organism.
