Regulation and Flexibility of Genomic Imprinting
... Genomic imprinting results in monoallelic gene expression in a parent-of-origin–dependent manner. It is achieved by the differential epigenetic marking of parental alleles. Over the past decade, studies in the model systems Arabidopsis thaliana and maize (Zea mays) have shown a strong correlation be ...
