From Wikipedia, the free encyclopedia. Epigenetics is the study of changes in gene activity which are not caused by changes in the DNA sequence. It is the study of gene expression, the way genes bring about their phenotypic effects.
A consensus definition of the concept of epigenetic trait as stably heritable phenotype resulting from changes in a chromosome without alterations in the DNA sequence was formulated at a Cold Spring Harbor meeting in 2008, although alternate definitions that include non-heritable traits are still being used.
