    In mosaic development: Cell Fate = Cell Potency. The fate of the cell is governed entirely by its intrinsic characteristics, i.e. cytoplasmic determinants it inherits at cell division. ... In regulative development :Cell Potency is greater than Cell Fate.

    Mosaic development results from the autonomous specification of a cell's fate. These cells, instead of depending on cell-cell interactions, are determined by cytoplasmic factors contained within the cell itself. In mosaic development: Cell Fate = Cell Potency. The fate of the cell is governed entirely by its intrinsic characteristics, i.e. cytoplasmic determinants it inherits at cell division. Regulative development depends in part on long-range gradients of positional information, such as that provided by the Hedgehog protein, that can pattern many cells at once. Regulative development generally occurs in early gastrulation when cells are induced to form different structures according to the cell-cell signaling interactions in a specific area of the embryo that lead to the conditional specification of a cell's fate.
