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 ...
This principle had been discovered by Douglas Spalding in the 19th century, and Lorenz's mentor Oskar Heinroth had also worked on the topic, but Lorenz's description of Prägung, imprinting, in nidifugous birds such as greylag geese in his 1935 book Der Kumpan in der Umwelt des Vogels ("The Companion in the Environment of Birds") became the ...
Partial imprinting occurs when alleles from both parents are differently expressed rather than complete expression and complete suppression of one parent's allele. [6] Forms of genomic imprinting have been demonstrated in fungi, plants and animals. [7] [8] In 2014, there were about 150 imprinted genes known in mice and about half that in humans ...
Erich Klinghammer was born in Kassel, Germany, where he received high school education.During this time in Germany, Erich was a member of the Hitler Youth. [2] He emigrated to United States in 1951 and served in the United States Army from 1953 to 1955, earning United States citizenship through military service, and returned to higher education at the University of Chicago with support from ...
Timber wolves and coyotes used as draught animals in northern Ontario, 1923. Wolves are less suitable than dogs for working. Swedish wolf biologist Erik Zimen once tried to form a dog sled team composed entirely of wolves. The experiment failed as the wolves ignored most commands and were far more prone to fighting than sled dogs. [6]
Upon hatching, birds will “imprint” They are cuddly, cute, and gregarious, but these attributes require a connection. Like many other animals, dogs form familial bonds with their owners.
Genomic imprinting is an epigenetic process by which certain genes are expressed in a parent-of-origin-specific manner. The imprinted brain theory is a variant of the kinship theory of genomic imprinting, also known as the conflict theory of genomic imprinting.
