Wing hairs in the most anterior region of the wing point towards the anterior margin in mutants, as opposed to distally as in wild type.
Wing margin bristles point out of the wing in fzunspecified
mutants, in contrast to wild-type, where they point to the distal end of the wing. Defects in wing hair polarity are seen and a few multiple wing hairs appear.
The abdomen of fzunspecified
homozygous flies does not completely lack planar polarity. Dorsally, the only obvious abnormality is dishevelment in the anterior portion of the A compartment with occasional whorls elsewhere, particularly in the front of the P compartment. However, ventrally, the hairs of the pleura lack all anteroposterior bias; in some places they are randomly oriented, in others they point mostly laterally.
Mutant clones in the wing show domineering non-autonomy: cells distal to the clone, as well as within the clone, show alteration of polarity of wing hairs.
Extreme tarsal phenotypes are seen, with complete duplications in T2-T4 and an ectopic joint structure in T1. Somatic clones in the wing cause long-range non-autonomous alteration in the polarity of cells, both distal and lateral to the clone, which tend to point towards the mutant clone.
Most wing cells of homozygous flies form a single hair. Homozygous flies have disruptions in the pattern of wing hair polarity. The prehair initiation site is moved to near the cell centre in pupal wing cells. Double mutants of fzunspecified
