From epi- +‎ genotype; compare epigenetic.


epigenotype (plural epigenotypes)

  1. The stable pattern of gene expression that is outside the actual base pair sequence of DNA.


  • Richard G. Ham and Marilyn J. Veomett, Mechanisms of Development,[1] Mosby (1980), ISBN 0801620228, page 331: “The inherited potential to express a particular type of differentiation has been termed the epigenotype of the cell. The implication of the term ‘epigenotype’ is that the predisposition of each cell to differentiate in a particular direction is a heritable characteristic that has somehow been superimposed on the basic genetic program of that cell.”
