    Frequencies of the nine <i>sechellia</i> markers in the six competition experiments over 20 generations.

    No full text
    <p>X-axis: generations. Y-axis: frequencies of <i>sechellia</i> markers. Each plot monitors the frequency of a single <i>sechellia</i> introgression relative to its <i>simulans</i> counterpart. A–C plots represent experiments with only a single introgression per genotype, while D1–F2 plots represent experiments with two <i>sechellia</i> introgressions per genotype, even though each plot follows only a single introgression/marker. Five experimental replicates for each marker. See <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1002795#pgen.1002795.s001" target="_blank">Figure S1</a> for introgression details.</p

    <p>The light bars represent <i>simulans</i> chromosome II or III, and the dark blocks represent <i>sechellia</i> introgression regions. Confirmed introgressions are shown in black. Unconfirmed introgressions are shown in grey. Microsatellite markers tracked in the experiment are labeled by the inverted triangles: A: DMU25686 (cytological position: 93F14); B: DRODORSAL (36C8); C: DROGPAD (47A9); D1: AC005732 (cytological position 24C9); D2: DMRHO (62A2); E1: DMMP20 (49F13); E2: DMCATHPO (75E1); F1: DS00361 (54B5); F2: DMU43090 (99D5) <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1002795#pgen.1002795-Macdonald1" target="_blank">[53]</a>, <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1002795#pgen.1002795-Colson1" target="_blank">[54]</a> (see <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1002795#s4" target="_blank">Materials and Methods</a> for details of each marker and for single versus double introgression designs).</p

    <p>Note: Fertility was measured by the total progeny produced by three pairs of flies for 15 days (N = 10).</p>*<p>Tukey-Kramer HSD value here shows significant difference between the sim132 <i>D. simulans</i> strain and introgression strains, taking into account multiple testing. It is equal to Abs(Mean[i]-Mean[j])-LSD. The value must be positive to be significant at <i>P-value</i><0.05. NS = not significant. All analyses were performed using JMP software (SAS). 25H line was lost before it could be tested.</p

    <p>Note: Labels inside parentheses for each introgression line indicate the experiment performed in <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1002795#pgen-1002795-g001" target="_blank">Figure 1</a>.
