Genomic imprinting is an epigenetic process that involves DNA methylation and histone methylation which doesn’t alter the genetic sequence but causes transcriptional silencing. Imprinting means marking a gene in the germline (sperm or ova) of the parents and which is maintained through mitotic cell divisions in the somatic cells of an organism. 2016-02-04 2018-04-12 This tutorial about DNA methylation explains the phenomena of genomic imprinting and the role of gene insulators in gene imprinting.For more information, log Genomic imprinting, the process by which the non-equivalence of the paternal and maternal genomes is established, has been fascinating us for over three decades and has provided many emerging scientists with the chance to hit their stride in a frontier posing many unexpected questions and even more surprising answers. This video describes the concept of imprinted genes, a set of specific genes that are expressed depending on whether they came from the mother or father. Mammalian genomic imprinting Normal mammalian development requires a maternal and paternal contribution, which is attributed to imprinted genes, or genes that are expressed from a single parental allele. Approximately 100 imprinted genes have been reported in mammals thus far. Imprinted genes are controlled by cis-acting regula … Abstract.

The ‘imprinted’ regions of the DNA are generally less active in transcription. Genomic imprinting is a process of silencing genes through DNA methylation.

Thus, genomic imprinting evolved in mammals with the advent of live birth. Its evolution apparently occurred because of a parental battle between the sexes to control the maternal expenditure of resources to the offspring (Haig, Altercation of generations: genetic conflicts of pregnancy.

Offspring normally inherit one maternal and one paternal copy of their genes, and generally both copies are active. The phenomenon of genomic imprinting, which results in some genes being expressed in a parental--origin-specific manner, is essential for normal mammalian growth and development and exemplifies Abstract. X chromosome inactivation and genomic imprinting are classic epigenetic processes that cause disease when not appropriately regulated in mammals. Whereas X chromosome inactivation evolved to solve the problem of gene dosage, the purpose of genomic imprinting remains controversial. Nevertheless, the two phenomena are united by allelic control of large gene clusters, such that only one copy of a gene is expressed in every cell. • Imprinted X inactivation: • Importantly, mammalian genes displaying genomic imprinting are distinguishable from genes that display apparent parental- specific expression due to unequal or unique genetic contributions from male and female parents such as the expression of Y-linked genes in XY males, the expression of maternally derived mitochondrial genes, and the expression of X-linked genes that evade the process of X-chromosome inactivation in XX females.
