Fig. 4. The wing phenotype of fry. A shows a fry¹ clone seen in the SEM. This micrograph was taken of an adult wing mounted on a stud without any metal coating. The clone boundary is outlined in white. The arrows point to hairs split distally. This is shown at approximately twice the magnification of the adult cuticle in C. (B) A fry² clone in a pupal wing stained with an anti-actin antibody to stain the developing hairs. The clone is marked by the loss of expression of the N-Myc epitope (clone cells do not stain green). The clone boundary is outlined in white. Note that only the clone cells show a fry mutant phenotype. A 2 µm size marker is shown. (C) A wing from a fry⁶/fry⁶ pharate adult. Note the strong fry mutant phenotype. (D) A confocal image of a fry⁶/fry⁶ pupal wing stained with Alexa 488 phalloidin to stain the actin cytoskeleton (this micrograph is shown at the same magnification as B).
