““As emphasized in the last chapter, epigenetic changes can be multi-generational.8 Dogma was that all the epigenetic marks (i.e., changes in the DNA or surrounding proteins) were erased in eggs and sperm. But it turns out that epigenetic marks can be passed on by both (e.g., make male mice diabetic, and they pass the trait to their offspring via epigenetic changes in sperm).””
About This Quote

Epigenetic modifications can survive the germ line and influence traits in subsequent generations, challenging the belief they are always reset.
In simple terms: Epigenetic marks can be inherited across generations.
