In 2014, there were ab Parental, or genomic, imprinting is a newly described form of genetic regulation, leading to the differential behavior of each parental copy of a gene. Genomic imprinting involves the epigenetic regulation of gene expression without altering the genetic sequence itself. In genes that undergo genomic imprinting, the parent of origin is often marked, or stamped, on the gene during This definition surely renders the observation of epigenetic inheritance easier, especially in humans, because it prevents the ambiguous interpretation of data that are inevitably contaminated by other events that are not transmitted epigenetically through gamete programming.

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.

WebInformation and translations of genomic imprinting in the most comprehensive dictionary definitions resource on the web. 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.
