Veomett, Mechanisms of Development,^[1] Mosby (1980), ?ISBN, 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.”
