Scatterplot of male vs. female ratios for Daphnia and Drosophila. D. pulex female/male ratios (females positive) are plotted on the X-axis and D. melanogaster female/male ratios (females positive) are plotted on the Y-axis. Genes with an e-value less than e-08 were considered homologs, and all D. pulex genes show significant differential expression between males and females. Numbers of genes with significant homology include 27 from e-08 to e-10; 21 from e-11 to e-20; 54 from e-21 to e-50; 33 from e-51 to e-80; and 15 at e-81 and lower.
