  • Fisher’s exact test was performed to detect enrichment or depletion of genes identified as sex-differentially expressed or genes identified as regulated by dsx, here, on each chromosome arm. The observed (Obs) and expected (Exp) number of genes are reported for each major chromosome arm, as well as the fold enrichment (Fold).
