"Imprinting genomowy, rodzicielskie piętno genomowe, naznaczenie genetyczne − polega na różnym stopniu metylacji genów i metylacji histonów w komórkach jajowych i komórkach plemnikowych. Gen jest metylowany na allelu pochodzącym od jednego z rodziców. Nakładanie imprintingu zachodzi w czasie gametogenezy. Wtedy jest znoszony wzór metylacji odziedziczony po rodzicach i nakładany nowy, zależny od płci. Do zmetylowanego nukleotydu nie mogą się prz… " - Imprinting cycle
