Fig. 10. Ectopic btd activity induces the production of morphogenetic signals in the wing and haltere discs. (A) Clone of btd-expressing cells in the wing disc showing en activity only in part of the clone (arrow, B). (C) Two clones in the haltere disc both showing en activity inside the clones but only in some cells (arrows, D). (E) Local gain of wg activity in a clone of btd-expressing cells. Only some cells show high wg levels (arrow, F). (G) Clone of btd-expressing cells in the hinge region of the posterior compartment showing gain of dpp activity in some cells (arrow, H).
