Evolution of male competitive performance.

<p>In <b>A</b>, the proportion of wild type progeny originated from the competition of experimental males with tester GFP males for the fertilization of standard females (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0035811#s4" target="_blank">Materials and Methods</a>). Dioecious populations are shown in blue, androdioecious populations in red. Empty circles show populations without initial genetic diversity and filled circles populations with initial diversity. Circles and bars represent the average values among replicate populations and associated SEM, respectively. Lines connect the least-square estimates (dots) obtained after ANOVA (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0035811#pone-0035811-t001" target="_blank"><b>Table 1</b></a> for analysis). In <b>B</b>, for the androdioecious populations without standing diversity (empty circles) the least-square estimates of male competitive performance (dots in panel <b>A</b>) are shown against the least-square estimates of male proportions observed (dots in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0035811#pone-0035811-g004" target="_blank"><b>Figure 4B</b></a>). The correlation among both phenotypes in these populations is positive and significant (<i>r</i> = 0.99; <i>t₂</i> = 9.2; <i>p</i> = 0.006). In gray the least-square estimates by replicate population at each generation from a fully nested model (<b><a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0035811#pone.0035811.s005" target="_blank">Table S3</a></b>). The correlation among these estimates is not significant. In <b>C</b>, as in <b>B</b>, for androdioecious populations with initial diversity (the correlations among phenotypes are not significant).
