Epigenetics refers to the study of heritable changes in gene expression that do not involve alterations to the underlying DNA sequence. The term was originally introduced in the 1940s to describe the regulatory interactions between genes and their cellular environment during development. It was intended to provide a conceptual framework that united genetics with embryology, two fields that had previously developed in parallel but separately.The early definition emphasized the role of regulatory
