From: Coevolution of the olfactory organ and its receptor repertoire in ray-finned fishes
Coevolution of the olfactory gene repertoire and number of olfactory lamellae. A OR genes. B TAAR genes. C OlfC genes. D Total olfactory receptor genes. The coefficient of determination (R2), the p-value (P), and regression line (solid line) of PGLS analyses are reported. Dot color code: red, Polypterus senegalus; brown Erpetoichthys calabaricus; light blue Polyodon spathula; dark blue Acipenser ruthenus; yellow Amia calva; dark green Atractosteus spatula; light green Lepisosteus oculatus; black teleosts
