Epigenetics is a field that studies changes in gene expression that do not involve alterations to the DNA sequence.
遺伝学 is the broader field of genetics, while 後成遺伝学 specifically refers to epigenetics, which deals with heritable changes beyond the DNA sequence.
Compound of 後成 (こうせい, 'epigenetic') + 遺伝学 (いでんがく, 'genetics'). The term is a direct translation of the English 'epigenetics'.
