Witryna16 lut 2024 · Reviewed by. Olivia Guy-Evans. Lorenz (1935) investigated the mechanisms of imprinting, where some species of animals form an attachment to the first large moving object that they meet. This process suggests that attachment is innate and programmed genetically. He took a large clutch of goose eggs and kept them … WitrynaImprinting disorder is the most relevant example of epigenetic variation causing diseases. Imprinting is a biological phenomenon in which certain genes are expressed in a parent-of-origin-specific manner due to epigenetic modification.
