The phenomenon of genomic imprinting evolved in a common ancestor to marsupials and eutherian mammals over 150 million years ago (Killian et al, M6P/IGF2R imprinting evolution in mammals. Mol Cell 5: 707-716, 2000). Thus, genomic imprinting evolved in mammals with the advent of live birth.

Genomic imprinting affects gene expression by chemically modifying DNA and/or altering the chromatin structure. Often, genomic imprinting results in a gene being expressed only in the chromosome inherited from one or the other parent. While this is a normal process, when combined with genomic mutations, disease can result. Genomic imprinting and uniparental disomy are factors that influence how some genetic conditions are inherited. Genomic imprinting, process wherein a gene is differentially expressed depending on whether it has been inherited from the mother or from the father. Such “parent-of-origin” effects are known to occur only in sexually reproducing placental mammals.

De viktig skillnad mellan X-inaktivering och genomisk imprinting är det X-inaktivering är den process genom vilken en kopia av X-kromosom inaktiveras hos vissa kvinnor, medan genomtryckning är en process som beror på ursprunget och det är processen där kopior av gener uttrycks differentiellt.

Imprinting defects can involve isolated or multilocus epigenetic changes that may have no evident genetic cause, or impri … Genomic imprinting is an example of epigenetics, or changes to DNA or chromatin that are inherited that do not affect the DNA sequence. Imprinting is achieved through DNA methylation, genomic imprinting The concept, derived from an increasing body of compelling evidence, that the expression of some of the genes depends on whether they have been derived from the father or from the mother.

Although ancestral donkey crossers would likely have no problem with the concept and reality of parental genomic imprinting, imprinting more recently carries an iconoclastic aura, evidence of the powerful influence Gregor Mendelès writings have exerted;indeed, the phenomenon of imprinting has been classified within the realm of non-Mendelian genetics, as if Mendels laws represent the Platonic genomic imprinting [DAVID HAIG: ]My work over the last decade or so has been principally concerned with conflicts within the individual organism. In a lot of evolutionary biology, the implicit metaphor is that the organism is a machine or, more specifically, a fitness-maximizing computer trying to solve some problem. Genomic Imprinting which is one of epigenetic events is suppression of some genes’ expression differs and this.
