This phenomenon may have a common basis with other unique features …

There is biased allelic expression due to imprinting that favors … WitrynaI believe that imprinting happens to keep the peace in the pack and to reinforce the protective instinct of the pack. As more and more wolves join the pack, more of them imprint. The fact that each of them finds their perfect match forever means that there will never be a fight between pack members founded on romantic rivalry.
In psychology and ethology, imprinting is any kind of phase-sensitive learning (learning occurring at a particular age or a particular life stage) that is rapid and apparently independent of the consequences of behaviour. It was first used to describe situations in which an animal or person learns the characteristics of some stimulus, which is therefore said to be "imprinted" onto the subject. Imprinting is hypothesized to have a critical period.

In genetics, changes that occur in a gene in passing through the egg or the sperm so … WitrynaSexual imprinting is widespread in birds and other species but its existence requires explanation. Our results suggest that sexual imprinting leads to speciation in locally- adapted populations if a neutral mating cue—e.g., novel plumage coloration—arises through mutation. Importantly, the mating cue locus is not linked to adaptation loci.
