From: Genomic and physiological responses to strong selective pressure during late organogenesis: few gene expression changes found despite striking morphological differences

Figure 4

Heat maps of differentially expressed genes due to population-by-treatment, treatment, and population effects among the reference and resistant embryos exposed to PAH-surrogate chemicals (Mixed model analysis ANOVA, p < 0.01). A) Expression patterns of 73 significant genes in population-by-treatment effect; B) 52 genes are significantly different due to a treatment effect; C) 26 genes are significantly different due to differences between reference and resistant embryo populations. Hierarchical clustering of genes based on the treatment is shown across the top of the heat maps. Red color indicates relative high expression levels and green represents low expression levels.
