<p>Correlations between gene duplicability and length and between gene duplicability and number of domains, in six species: <i>H. sapien</i> (Hsap), <i>M. musculus</i> (Mmus), <i>D. melanogaster</i> (Dmel), <i>C. elegans</i> (Cele), <i>S. cerevisiae</i> (Scer), and <i>E. coli</i> (Ecol). The numbers of gene families and genes for each of the six species are the same as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0044491#pone-0044491-t001" target="_blank">Table 1</a>. The value is Spearman’s rank correlation coefficient between duplicability and connectivity, and the -value is computed for the correlation.</p
