Summary
Epigenetics: the study of heritable changes in gene expression that cannot be explained by changes in DNA sequence.
Leads to an improved understanding of:
1. Mechanisms underlying natural phenotypic variation
2. Responses of organisms to environmental change
Further, more extensive research is needed as this is a relatively new, but fast growing branch of science that little is known about thus far.
The image below links to a dynamic presentation entitled “Epigenetics Explored” that I was heavily involved in creating and presenting. It served as a short introduction of main epigenetics concepts to a peer audience.
