zig-3 mutant phenotype. (A) PVQ flip-over defects observed with the oyIs14 reporter transgene. Most (>90%) of all axon flip-over defects observed in zig-3 (or zig-4) mutant animals occur in the posterior half of the animal. (B) Quantification of zig-3 mutant defects at different developmental stages and under different experimental conditions. Proportions of different animal populations were compared using the z-test. *P < 0.05.
