Webgenomic imprinting: epigenetic process that leads to inactivation of paternal or maternal allele of certain genes susceptible to epigenetic regulation; accounts, among others, for The term imprinting was taken from physiology. According to the classical definition, coined by Conrad Waddington in 1942, Genomic imprinting is an epigenetic phenomenon, which is related to differential parent-of-origin gene expression. Epigenetic modifications originating in the sperm or egg cell that lead to the methylation ( and therefore lack of expression) of one of the parent's alleles.

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. genomic imprinting . Definition in the dictionary English. Genomic imprinting is an epigenetic alteration (i.e., not involving a change in base sequence) of a specific parental allele of a gene, or the chromosome on which it resides, in the gamete or zygote, leading to differential expression of the two alleles of the gene in somatic cells of the offspring. Most of the imprinted genes identified so far are physically linked in clusters and coordinate regulation. Examples of animals that imprint include ducks, chickens, turkeys, penguins, and geese. Imprinting in animals is a form of learning that occurs during a critical period early in development. It is a special type of behavior where an animal learns to identify with and follow the first moving object it sees after birth or hatching. . Genomic imprinting is an epigenetic phenomenon. Genomic imprinting. - 22 , : . Genomic imprinting: The phenomenon of parent-of-origin gene expression. genetic alteration of a gene or its expression that is inferred to take place from the observation that certain genes are expressed differently depending on whether they are inherited from the paternal or maternal parent. Imprinting means that that gene is silenced, and gene from other parent is expressed. The mechanisms for imprinting are still incompletely defined, but they involve epigenetic modifications that are erased and then reset during the creation of eggs and sperm.
