Answer :

The environmental influences on gene expression best illustrates the need for research on epigenetics.

Genes have very prominent role in diseases which are affected by environmental factors. People suffer from anxiety and depression due to gene mutation, however such conditions are rare. Scientists are researching on the potential conditions which affect gene. Epigenetics is the field of scientific research which correlates the the behaviors and the  environmental conditions which prominently describes the gene expression. However, epigenetic changes are reversible in nature and they do not change the DNA sequence in the body as it occurs during mutations due to radio waves which encounters the body. Epigenetic changes are modifications to DNA that regulate whether genes are turned on or off.
