## Figure 2.
All possible direct comparisons of map length between paired control and coevolved
lines. The graph covers thirteen corresponding (paired) intervals (x-axis). To account
for zero values, one observation was added to all recombinant counts and to all total
counts; hence, recombination frequency is calculated as: n_{recombinants }+ 1/n_{total }+ 1. Recombination frequencies were transformed into map distances. Shown is the significant
logarithmic relationship between the relative difference in percentages of coevolved
(NL) and control lines (CL), and the observed map lengths in the control lines (linear
regression, n = 13, F_{1, 11 }= 10.188, P = 0.009, R^{2 }= 0.481). This indicates that observed recombination frequencies are higher in coevolved
lines compared to control lines. Symbols indicate from which line each data point
originates: a triangle for line 3, a square for line 4, a circle for line 5, a diamond
for line 6.
