  • a The gene-trap vector was integrated into the CyO chromosome.

  • b The ratio of the number of established lines over that of total jump-started mosaic-eyed males shown in the top row.

  • c The percentage of gene-trap lines with Gal4 expression relative to the total stocks with vector insertions,which are given in the middle row.
