Distribution of differentially abundant antennal Ors and their relative abundance levels in An. gambiae and An. quadriannulatus . Individual tuning Or orthologs are represented by bubbles with areas scaled to their respective abundance (RPKM) in either An. gambiae (red) or An. quadriannulatus (blue). Or orthologs are arranged horizontally based upon their enrichment (GFOLD value) in either An. gambiae (left) or An. quadriannulatus (right). Total RPKMs for each quadrant are indicated in the center. The asterisk denotes the larger than expected proportion of Or abundance in An. gambiae ascribable to Ors that are also enriched in An. gambiae (Fisher’s Exact Test, p=2.2x10^-16).
