obsolete regulation of gene expression by genomic imprinting https://github.com/geneontology/go-ontology/issues/22217 https://github.com/geneontology/go-ontology/issues/25567 true regulation of gene expression by genetic imprinting biological_process GO:0006349 This term was obsoleted because it represents the same concept as its parent, GO:0071514 genomic imprinting, also a regulatory process. regulation of gene expression by DNA imprinting OBSOLETE. An epigenetic mechanism of regulation of gene expression in which epigenetic modifications (imprints) are established during gametogenesis. For a given gene to show parentally biased expression, the imprint are established exclusively in one of the two parental genomes, thus generating an asymmetry between the maternal and paternal alleles.
