^aCoverage by Exelixis or DrosDel deletion stocks maintained at the BDSC. Some deletions reported by Exelixis [5] were false positives; stocks for other deletions were lost. Stocks for some DrosDel deletions [9] were too weak to maintain. ^bCoverage provided by BSC deletions, but not Exelixis or DrosDel deletions. ^cChemical- or irradiation-induced deletions plus FRT-derived deletions from individual investigators.
