Clones in the wing disc expressing en^αTub84B.PZ and of posterior origin are strictly confined to the posterior territory. 8 out of 16 clones expressing en^αTub84B.PZ and of anterior origin occupy positions normally taken only by posterior cells.

Clones expressing en^αTub84B.PZ that span a small area in the male external genitalia cause duplications of bristles. A large number of this type of clone are seen on the lateral lobe and claspers. Clones spanning a larger area in the male external genitalia result in pattern reorganisation of the neighbouring areas in a mirror image symmetry. The penis apparatus also shows duplications of various parts including the hypandrium, hypandrial bristles and apodeme. In females, clones produce mirror image duplication of thorn bristles and of the long bristles in the opposite direction in the vaginal plates. In some cases the thorn bristles are absent. The cells expressing en^αTub84B.PZ contribute to only a small portion of the altered pattern.

Expression of en^αTub84B.PZ in the anterior compartment of the haltere causes its transformation to wing.

Clones expressing en^αTub84B.PZ in the posterior tergite are transformed into posterior hairy zone (PHZ), whereas more anterior clones contain both PHZ and intersegmental membrane (ISM). Ectopic ISM is always induced anteriorly to ectopic PHZ, and is never induced posterior to the second row of microchaetae. Larger clones cause wild-type cells at the posterior of the clone to produce posterior tergite structures. Clones in the anterior tergite produce PHZ with reversed trichome orientation, while clones in the posterior tergite produce PHZ with normal polarity.

Wing clones in the posterior compartment develop normally. Wing clones in the anterior compartment fall into two types: neutral and reorganizing. Neutral clones are morphologically normal and small or close to the compartment boundary. Reorganizing clones are found in the anterior and are larger than neutral clones in corresponding positions. Where reorganizing clones contribute to dorsal and ventral surfaces they cause a symmetric reorganization of pattern. Where reorganizing clones are restricted to dorsal or ventral surfaces do not alter the size/shape of the wing, but alter the behavior of surrounding anterior cells on the same surface e.g. to cause circular veins. Response of cells to the clone depends on the distance from the clone. Altered wing pattern is similar to that seen for hh^αTub84B.PB though cells in en^αTub84B.PZ clones behave like posterior cells rather than anterior cells as in hh^αTub84B.PB clones. Clones spanning the normal position of the copmpartment boundary sometimes fail to form part or all of the longitudinal vein 4.
