Temporal variation in expression of protein products of three eyespot-associated genes.

<p>Comparisons of Notch (A), Engrailed (B), and Distal-less (C) expression in two forms of <i>B. anynana</i>. Graphs show logistic curves fit to observed expression in each of the two forms. Images show expression in dry season and wet season wing discs of the same developmental stage; N_D and N_W reflect total compartments examined in dry and wet season wing discs, respectively. In (A) and (B), white arrows in dry season images indicate compartments with focal expression of respective proteins; black arrows indicate corresponding compartments in wet season wing discs, which lack focal expression at this stage.
