Figure 1

Typical examples of PCP features in Drosophila. PCP effects in the wing (a,b) and eye (c,d). Wild type is shown in panels a and c (note the regular arrangements in both tissues), and the mutant appearance (fz−) of same tissues is shown in b and d. (c and d) The right panels show the orientation of ommatidia schematically by arrows: black and red arrows represent the dorsal and ventral orientations (not mirror image symmetry in wild type/c) and loss of it in the mutant scenario. Occasional symmetrical ommatida (green arrow) are also found in the mutants.
