The percentage of gametogenesis-related GO terms among the GO terms with significant representation (p < 0.05) among the initial set of 454 Drosophila orthologs (gray) and the post-filtering subsets of genes; the absolute numbers are above the bars. Color coding: light purple—mutant phenotype filter (filter 1, 25 genes); intermediate purple—filter based on relative levels of testicular expression (filter 2, 108 genes); and dark purple—filter based on relative and absolute levels of testicular expression (filters 2 + 3, 71 genes). As we applied the successive filters, the GO terms were progressively enriched with terms related to gametogenesis
