From: Genomic imprinting – an epigenetic regulation of fetal development and loss
The effect of genomic imprinting on protein production. (A) A normal, non-imprinted gene where the speed-limiting regulatory protein bind to equal extent to the two gene copies. (B) An imprinted gene, where one of the parents copy is subject to imprinting, which int erferes with the binding of the regulatory protein. Consequently, no protein is produced from the silenced, imprinted allele.
