Genomic imprinting-the non-equivalence of maternal and paternal genomes-is a critical process that has evolved independently in many plant and mammalian species1,2 . According to kinship theory, imprinting is the inevitable consequence of conflictive selective forces acting on differentially expressed parental alleles3,4 . Yet, how these epigenetic differences evolve in the first place is poorly understood3,5,6 . Here we report the identification and molecular dissection of a parent-of-origin effect on gene expression that might help to clarify this fundamental question...
