Genetically identical mice with different DNA methylation patterns causing kinks in the tail of one but not the other.<unk>  is the transmission of epigenetic markers from one organism to the next (i.e., from parent to child) that affects the traits of offspring without altering the primary structure of DNA (i.e. the sequence of nucleotides)—in other words, epigenetically. The less precise term "epigenetic<unk> " may cover both cell–cell and organism–organism information transfer. Although these two levels of epigenetic<unk>  are equivalent in unicellular organisms, they may have distinct mechanisms and evolutionary distinctions in multicellular organisms. Environmental factors can induce the epigenetic marks (epigenetic tags) for some epigenetically influenced traits, while some marks are heritable, thus leading some to consider that with epigenetics, modern biology no longer rejects the<unk>  of acquired characteristics (Lamarckism) as strongly as it once did.
