Gene Ontology terms significantly enriched among genes that were differentially expressed in ventricles from juvenile snapping turtles that had been incubated in normoxic or hypoxic conditions as embryos. Enrichment analysis was carried out on all 443 genes that were affected by oxygen concentration during embryogenesis (Table 2), the oxygen concentration by age interaction (Table 3), and/or those genes that differed between ventricles from turtles that had normal-sized vs. enlarged hearts relative to their body size (Table 4). The number of genes for each GO term is represented by the size of the circle, while the FDR adjusted p value is shown by the color of the circle
