Introduction. Genomic imprinting is an epigenetic regulatory phenomenon in which there is allele-biased expression of certain genes depending on the parent of origin. 1 Imprinted gene expression plays a role in fetal growth regulation and postnatal behaviour in mammals, formation of viable seeds and the inhibition of … For example, the gene encoding insulin-like growth factor 2 (IGF2/Igf2) is only expressed from the allele inherited from the father. Although imprinting accounts for a small proportion of mammalian genes they play an important role in embryogenesis particularly in the formation of visceral … Zobacz więcej Genomic imprinting is an epigenetic phenomenon that causes genes to be expressed or not, depending on whether they are inherited from the mother or the father.
