  • The above data are derived from Figure 3C, where the cumulative numbers of rod precursors born and rhodopsin-positive precursors were approximated for each day of retinal development. From these data, the lag between rod precursor genesis and onset of rhodopsin expression was determined. Each data point represents the average ± SEM, except where indicated.

  • F1-a In this column, data were derived fromn = 2, except where indicated by an asterisk (*) where a single trial was performed.

  • F1-1002 In this column, data were derived fromn = 2–6.
