Imprinting biology definition
WitrynaFilial imprinting is a process, readily observed in precocial birds, whereby a social attachment is established between a young animal and an object that is typically (although not necessarily) a parent.

Imprinting. Imprinting is a simple and highly specific type of learning that occurs at a particular age or life stage during the development of certain animals, such as ducks and geese. When ducklings hatch, they imprint on the first adult animal they see, typically their mother.
WitrynaImprinting is the process in which a newborn animal forms a bond with its caregiver, most commonly its parents. True imprinting is found mostly in birds that are precocial, or able to walk soon after birth, but it can also be seen to an extent in some mammals. Witryna14 sie 2013 · Genomic imprinting is an epigenetic mechanism of inheritance which allows genes to be expressed differently depending on which parent they come from. This means it is modification of the genome, or changes what the genome produces, without changing the nucleotide (DNA) sequence.
