Question

Quizplus · Accepted Answer

Genomic imprinting is a phenomenon where certain genes are expressed based on their parental origin. This is due to epigenetic marks that are placed on the DNA during gamete formation, which distinguish the maternal and paternal chromosomes. Therefore, imprinting marks the parental origin of alleles.
