Genes were detected by BLAST protein homology searches using annotations and literature available at FlyBase [26]. Evidence for gene expression (indicated by "Yes" or "No") was determined using cDNA from pooled genotypes of cyclical parthenogens producing either resting eggs (via meiosis) or direct-developing eggs (via parthenogenesis). Expression patterns between meiosis and parthenogenesis were indistinguishable.
