The variation of peak frequency of <i>A</i> and <i>B</i> colonies in the paired experiment (mean ± SD, n<sub>1</sub> = n<sub>2</sub> = 6).

<p>The asterisks indicate significant differences (medians and 95% credible intervals). A Bonferoni correction was used in the intra-group variation, and an independent-samples t-test was used to test the differences between groups. Paired condition: A<sub>1</sub>-B<sub>1</sub>, A<sub>2</sub>-B<sub>2</sub>, A<sub>3</sub>-B<sub>3</sub>, A<sub>4</sub>-B<sub>4</sub>, A<sub>5</sub>-B<sub>5</sub>, A<sub>6</sub>-B<sub>6</sub>.</p>
