The variation of peak frequency of A and B colonies in the paired experiment (mean ± SD, n1 = n2 = 6).

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: A1-B1, A2-B2, A3-B3, A4-B4, A5-B5, A6-B6.
