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…

Imprinted biology

WitrynaImprinting and Parthenogenesis. Imprinting is the reason that parthenogenesis ("virgin birth") does not occur in mammals. Two complete female genomes cannot produce viable young because of the imprinted genes. For example, the embryo needs the father's Igf2 gene because the mother's copy has been imprinted and is inactive.
