Fig. 2. The wing development pathway is disrupted at multiple points to create
wingless ants. Activity (as measured by gene expression) of genes involved in
wing development is shown for ant imaginal wing discs that will and will not
produce wings in the adult animals. In these networks, boxes represent genes
shown in Fig. 1C and lines
indicate regulatory interactions among genes. Green indicates similar
expression to D. melanogaster, red indicates divergent or absent
expression, and grey indicates genes that were not surveyed. This figure is
adapted from Abouheif and Wray (Abouheif
and Wray, 2002).
