Witryna29 wrz 2024 · 1. Background. Newborn nidifugous birds such as ducks and chickens quickly learn to identify their mother and follow her around for protection, warmth and foraging information, a phenomenon known as filial imprinting [ 1 ]. As a learning mechanism, imprinting is notable because it lacks explicit (observable) reinforcement … WitrynaImprinted genes are expressed in a monoallelic, parent-of-origin-specific manner. Clusters of imprinted genes are regulated by imprinting control regions (ICRs) characterized by DNA methylation of one allele. This methylation is critical for imprinting; a reduction in the DNA methyltransferase DNMT1 causes a widespread loss of …
