Eipigéineolaíocht
Sa bhítheolaíocht, is éard is eipigéineolaíocht ann ná an staidéar ar athruithe ar léiriú na géine atá le fáil le hoidhreacht go miotóiseach agus nach dtarlaíonn athrú sa tseicheamh ADN air dá mbarr.[1] Tugann an réimír Sean-Ghréigis: epi- (ἐπι- "thar, lasmuigh de, timpeall") sa téarma eipigéineolaíocht le tuiscint go bhfuil gnéithe “ar bharr” nó “sa bhreis" ar an bhonn géiniteach traidisiúnta le haghaidh oidhreachta.[2]

PMID 19711245. “In the original sense of this definition, epigenetics referred to all molecular pathways modulating the expression of a genotype into a particular phenotype. Over the following years, with the rapid growth of genetics, the meaning of the word has gradually narrowed. Epigenetics has been defined and today is generally accepted as 'the study of changes in gene function that are mitotically and/or meiotically heritable and that do not entail a change in DNA sequence.'”
