Shading in the chimeras indicates the ato domains. The numbers of ectopic ch (column 4) and es (column 5) organs in the basal one-quarter of the wing are given as mean ± SEM. The numbers of ectopic ch organs divided by the total number of ectopic sensory organs are given as percentages in column 6. The total number of wings and independent lines assayed for each construct are given in columns 7 and 8, respectively.
