Fig. 3. Derepression of 22UZ Zeste and 22UZ GAGA transgenes in Pc³ mutant embryos. (A,B) 22UZ GAGA. (C,D) 22 UZ Zeste. Expression in wild-type embryos is shown on the left (Wt). Expression in Pc³ embryos in shown on the right (Pc3). The arrowheads mark the anterior and posterior boundaries of Ubx expression in wild-type embryos. The increased expression to the left of the anterior arrowhead in Pc³ homozygous embryos shows the derepression of the transgenes. All embryos were stained for the same length of time.
