Figure 2

Cone opsin gene distributions in tilapia, Oreochromis niloticus , inferred from microspectrophotometric cone distributions (white bars) or quantified by quantitative reverse transcription polymerase chain reaction (black bars). The number of cones quantified by microspectrophotometry is labeled for each white bar. These came from 15 different individuals. Gene expression was averaged over several individuals at each stage: 20–26 dpf (n = 8), 28–30 dpf (n = 5), 40–48 dpf (n = 2), >4 months (n = 4).
