Genomic imprinting is an epigenetic phenomenon that causes genes to be expressed or not, depending on whether they are inherited from the mother or the father. Genes can also be partially imprinted. Partial imprinting occurs when alleles from both parents are differently expressed rather than complete expression and complete suppression of one parent's allele. Forms of genomic imprinting have been demonstrated in fungi, plants and animals. In 2014, ther… WebJan 1, 2000 · Family study data are inconsistent with a single major gene and indicate instead a model involving a small number of epistatic loci. But they do not explain the …

WebFeb 16, 2024 · This process is known as imprinting, and suggests that attachment is innate and programmed genetically. Lorenz believed that once imprinting has occurred, it cannot be reversed, nor can a gosling imprint on anything else. To ensure imprinting had occurred, Lorenz put all the goslings together under an upturned box and allowed them to mix. WebImprinted genes are known to play an important role in normal fetal and behavioral development. The gene is expressed only on the X-chromosome that is inherited from the father and raises the threshold for phenotypic expression. It is normally silenced when transmitted maternally.
