- La herencia estructural o cortical es la transmisión de rasgos epigenéticos entre los seres vivos mediante la autogeneración de estructuras biomoleculares, en contraste con la transmisión genética de las secuencias de ADN, basada en el apareamiento de bases, que contribuye a la mayor parte de la variación genética entre organismos.

- Structural inheritance or cortical inheritance is the transmission of an epigenetic trait in a living organism by a self-perpetuating spatial structures. This is in contrast to the transmission of digital information such as is found in DNA sequences, which accounts for the vast majority of known genetic variation. Examples of structural inheritance include the propagation of prions, the infectious proteins of diseases such as scrapie (in sheep and goats), bovine spongiform encephalopathy ('mad cow disease') and Creutzfeldt–Jakob disease (although the protein-only hypothesis of prion transmission has been considered contentious until recently). Prions based on heritable protein structure also exist in yeast. Structural inheritance has also been seen in the orientation of cilia in protozoans such as Paramecium and Tetrahymena, and 'handedness' of the spiral of the cell in Tetrahymena, and shells of snails. Some organelles also have structural inheritance, such as the centriole, and the cell itself (defined by the plasma membrane) may also be an example of structural inheritance. To emphasize the difference of the molecular mechanism of structural inheritance from the canonical Watson-Crick base pairing mechanism of transmission of genetic information, the term 'epigenetic templating' was introduced.
