Loss of both chw-1 and sax-3 increases PDE axon pathfinding defects. Loss of both chw-1 and sax-3 increases PDE axon pathfinding defects. Quantitation of PDE defects. lqIs2 is the osm-6::gfp control transgene. The Y-axis denotes the genotype and the X-axis represents the percentage of ectopic lamellipodia formation. At least 100 neurons were scored for each genotype. *P < 0.0001 as determined by Fisher Exact Analysis. The error bars represent the standard proportion of the mean. Jamie K. Alan et al.
