Fig. 7. eyg and ey can function independently. (A) In the
ey2 mutant, E132>eyg can cause an
ectopic ventral eye, similar to E132>eyg in the wild-type
background. (B) In the eygM3-12 mutant,
dpp>ey can cause ectopic eye formation on wings, legs and
antennae, similar to the effect of dpp>ey in wild-type
background.
