Imprinting biology examples
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, the… WitrynaPreeclampsia, for example, in which disordered imprinting has been implicated, also demonstrates growth restriction in utero. Many of these diseases can be understood only within the context of imprinting as a common mechanism of parental conflict and manipulation of the phenotypic outcome of children.
