Abstract

‘Imprinting’ is a mechanism causing differential expression of the parental alleles of certain genes during embryonic and postnatal development in mammals and during seed development in angiosperm plants. Imprinting evolves due to the reduced genetic relatedness of paternal, relative to maternal, alleles at loci influencing maternal investment in the offspring of polygamous females.
