Relative intensity of M- or S-opsin in a cone population (X-axis) is displayed as a function of dorsal to ventral position. Each point is colored according to the log10[Probability] of expression levels. (A-E) Relative intensity of M-opsin expression (F-J) Relative intensity of S-opsin expression (A, F) All M-opsin expressing cells. (B, G) All S-opsin expressing cells. For (B), arrow heads mark two distinct groups of cells in the dorsal region. (C, H) CEC cones co-expressing both S- and M-opsins. (D, I) M-opsin only expressing CEC cones. (E, J) S-opsin only expressing CEC cones.</p
