Experimental protocol used in tests of divorce.

<p>Male heterozygosity was calculated for each clone as the number of heterozygous loci divided by the total number of loci. Genetic similarity was estimated using the r coefficient of Wang <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003328#pone.0003328-Wang1" target="_blank">[20]</a>. ΔH represents the difference between the heterozygosity of the newcomer male and the heterozygosity of the first male. ΔD represents the difference between the genetic similarity between the first male and the female and the genetic similarity between the newcomer male and the female.</p>*<p>indicates that one mouse died before the end of the experiment.</p

Differences in mean divorce rate corrected by numerical ‘pressure’ (±SE), according to which sex is given opportunities to divorce.

<p>The numerical ‘pressure’ is measured as the number of individuals introduced during the second infection divided by the number of individual of the same sex introduced on the first one.</p

Qualitative protein identifications in a comparative screen among A10, A35 and A4 S. mansoni adult clones

For each spot, the name(s) of protein(s) identified, species and database accession numbers, peptide number and MASCOT score are reported. *: signal anchor and signal peptide (SP) were predicted using SignalP 3.0
