Imprints in the history of epigenetics - Nature

WitrynaThese imprinted genes play an important role in embryonic and extraembryonic growth and development, as well as in a variety of processes after birth. Many imprinted genes are clustered in the genome with the establishment and maintenance of imprinted gene expression governed by complex epigenetic mechanisms. 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. WitrynaICRs (yellow star) can affect the imprinting of several imprinted genes in a cluster, resulting in a switch in the epigenotype, with the maternally inherited chromosome acquiring epigenetic characteristics and expression patterns typical of the paternal one (or vice versa).
