Morphogens like bicoid often have a gradient that is considerably less precise than the final read-out in the embryo (for instance the precise expression of Engrailed and Wingless at the cell-by-cell level). Discuss how the segmentation pathway is able to handle the variations in bicoid gradients to establish the precise pattern of expression seen in the expression of even-skipped.
