The current molecular explanation for imprinting in mammals involves differential methylation of various DNA regions. Imprinting involves the epigenetic modification of certain genes, where one allele is silenced, and only the other allele is expressed. This often occurs through DNA methylation, where methyl groups are added to cytosine residues in certain regions of the genome, resulting in gene silencing.
