Genomic imprinting occurs in

Answer: Option D

Genomic imprinting occurs in Plants, Animals, and Humans.
Genomic imprinting is a process of silencing genes through DNA methylation. The repressed allele is methylated, while the active allele is unmethylated.
Genomic imprinting refers to a form of epigenetic gene regulation whereby alleles are differentially expressed in a parent-of-origin-dependent manner.
Imprinting evolved independently in flowering plants and therian mammals in association with the elaboration of viviparity and a placental habit.
