Table 2. Wing Margin Phenotypes of en-Gal4; UAS-fz1/2 Chimeras.

Note dsh dosage sensitivity of the Fz1–1-1-induced wing nick frequency and size by removal of one copy of dsh, and the correlation of a dominant negative effect with apical localization (e.g., presence of Fz1 or Fz2S C-tails; compare also to Table 1). “Large nick” is defined as an area of the wing lacking more than 20 margin bristles
