*Determined by assessment of alignment overlap of data category versus gene model. ^†Not including those contributed by the BDGP (not mutually exclusive categories: many of these genes also have representative cDNA clones in the DGC). ^‡ARGS, annotated reference gene sequence; high-quality FlyBase gene-level annotations that include data from the published literature; contributed to the NCBI reference sequence (RefSeq) project. ^§For a rigorous assessment of the quality of the DGC cDNAs, see [30].
