<i>slik</i> Mutant Clones in Adult Wings

(A and B) Cuticle preparations of adult wings from w f36a hs-FLP1/Y; FRT42D P(f+) P(f+) M(2)l2/FRT42D slik1 larvae. (A) Adult wing from a larva not subjected to heat shock to induce clones. (B) Wing with large homozygous Minute+ slik1 mutant clones. Note the small size of the wing and the vesicles of black necrotic tissue between the layers of the wing. (C) Detail of a clone in the wing margin. Mutant cells, marked by forked, differentiate as normal wing margin bristles (arrows). (D) Detail of a clone in the wing blade. Mutant cells differentiate as normal wing blade and wing vein cells. The boundary of the clone in the vein is indicated by the dashed red line. (E and F) slikKG04837/slik1 wings. In (E), the arrow indicates a small vesicle in a mildly affected wing.
