Identical twins have the same set of epigenetic marks on the genome when they are born.

One is simply the well- known fact that epigenetic marks are lost as people get older.

This is accomplished by preserving the epigenetic marks, specifically H3K4me3, established by maternally-supplied factors.

In mammals, epigenetic marks are erased during two phases of the life cycle.

The epigenetic marks of the male are rapidly diluted.

Cellular mechanisms may allow for co-transmission of some epigenetic marks.

Inherited epigenetic marks may be important for regulating important components of fitness.

In animals, numerous studies have shown that inherited epigenetic marks can increase susceptibility to disease.

Adults who were conceived during the famine had distinct epigenetic marks that their siblings born before or after the famine did not.

These epigenetic marks are established in the germline and are maintained throughout all somatic cells of an organism.
