Conditional coexpression analysis: Preservation of modules in the GCNs underlying oral (OJA) and lower pharyngeal jaw apparatus (LPJA). a The colours represent identified OJA coexpression modules. Preservation of genes found in OJA modules in the LPJA coexpression network was calculated by a Zsummary statistic (y-axis) based on a permutation test that takes into account the connectivity and density of genes in a module. Zsummary < 2 represents lack of preservation (dotted blue line). Zsummary between 2 and 10 implies moderate preservation. Zsummary > 10 supports strong preservation of module. b Visual representation of module preservation. The upper panels of the dendrogram represents average linkage clustering tree based on topological overlap distance in gene expression profile. Each ‘leaf’ of the dendrogram corresponds to one gene. The lower panels of the dendrograms represent colours that correspond to OJA modules Top: OJA modules in the OJA GCN. Bottom: OJA modules in the LPJA GCN
