    • Abstract

       

      Twenty five years ago it was proposed that conserved components of constitutive heterochromatin assemble heterochromatinlikecomplexes in euchromatin and this could provide a general mechanism for regulating heritable (cell-to-cell) changesin gene expressibility. As a special case, differences in the assembly of heterochromatin-like complexes on homologouschromosomes might also regulate the parent-of-origin-dependent gene expression observed in placental mammals. Here,the progress made in the intervening period with emphasis on the role of heterochromatin and heterochromatin-likecomplexes in parent-of-origin effects in animals is reviewed.
