Representative tests of penetrance, absolute and relative fitness.

<div><p>High (red) and low (blue) lines, genetically differentiated for <i>dfe</i> penetrance were not differentiated by tests of viability and fitness.</p> <p>Controls (grey) were either <i>Canton-S</i> (<i>CS</i>) flies tested at the same time or published values for wild-type flies (WT; <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0000076#pone.0000076-Ashburner1" target="_blank">[21]</a>).</p> <p>Experiments showing the most extreme between line differences are displayed.</p> <p>Error bars indicate the standard errors of the mean.</p> <p><b>A.</b> Penetrance of eye deformity in <i>dfe</i> lines and <i>CS</i> flies reared at 25°C.</p> <p><b>B.</b> Hatch rate of timed embryo collections measured at 36 hours post egg-laying.</p> <p><b>C.</b> Egg-to-adult survival measured as the number of adult flies emerging versus eggs laid.</p> <p><b>D.</b> Fractional survivial of <i>dfe</i> progeny in competition with <i>CS</i> flies co-cultured at high density.</p> <p><b>E.</b> Lifetime female production of eggs (wild-type values; <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0000076#pone.0000076-Ashburner1" target="_blank">[21]</a>) or viable adult offspring (high and low line <i>dfe</i> females).</p>
