Name genomic imprinting: Exact Synonyms DNA imprinting | genetic imprinting: Definition : The establishment of epigenetic modifications (imprints) during gametogenesis, leading to an asymmetry in the heterochromatin between the maternal and paternal alleles, and differential expression of the corresponding alleles. Genes can also be partially imprinted. Definition. 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. It does not store any personal data.
