SNP density (a) and expression (b) of effector genes and gene copy number variants. Effectors found within repetitive regions were not significantly associated with SNP changes, although both effectors and secreted genes in any region of the genome were frequently up and downregulated in expression. Significance was calculated with Fisher’s exact tests in the GeneOverlap R package, and significance at <0.05 is *, <0.01 is **. Expression is represented as a log fold change of expression in a comparison of pre-parasitic and parasitic J2 nematodes
