In mammals and plants, parental genomic imprinting restricts expression of certain loci to one parental allele. In mammals, imprinted genes affect various aspects of maternal care and nutrition of offspring from embryogenesis until adulthood. In plants, the expression of imprinted genes is mostly restricted to the endosperm, which nurtures the embryo. Although this restricted domain of expression suggests that the selection of imprinted genes is related to their role in endosperm, supporting… CONTINUE READING
