Here's your answer

Epigenetics – It's not just genes that make us. Quick look: In its modern sense, epigenetics is the term used to describe inheritance by mechanisms other than through the DNA sequence of genes. ... It works through chemical tags added to chromosomes that in effect switch genes on or off.

One example of an epigenetic change is DNA methylation — the addition of a methyl group, or a "chemical cap," to part of the DNA molecule, which prevents certain genes from being expressed. Another example is histone modification. Histones are proteins that DNA wraps around

Epigenetic means the study of changes in organisms caused by modifications of gene expression rather than alterations of the generic code itself
