Figure 4From: Common peptides shed light on evolution of Olfactory ReceptorsCP coverage of positions along the OR sequence for selected species. CPs coverage of positions along the OR sequence for pufferfish (A), zebrafish (B), Frog (C) and Human (D). Thresholds mark the regions that are common to all ten species (B) and new to vertebrates (D). Positions are the same as in Figure. 3.Back to article page
