Witryna26 lut 2024 · Genomic imprinting is an epigenetic phenomenon that differentiates maternal and paternal copies of genes in the genome and causes monoallelic expression depending on parental origin. Imprinting is an evolutionary puzzle, as it bears the costs of diploidization without its advantages, namely, protection from recessive mutations. WitrynaGenomic imprinting attracted particular attention in the 1980’s following the discovery that the parental origin of genetic information is essential for normal development of eutherians,1,2 for review see.3 The term imprinting was first introduced in the 1960s to describe the elimination of the paternal chromosomes during spermatogenesis in the …
