Abstract: Genomic imprinting is a parentoforigin specific gene expression which is a vital epigenetic mechanism. This article reviews the characters of imprinting genes and the mechanisms of genomic imprinting. It also demonstrates the biology significance of genomic imprinting.

Key words: genome imprinting; DNA methylation; modification of histones; biological significance
