Table 3.
Among-generation comparison of the direction of adjacent pairwise Linkage disequilibrium alteration under field exposure compared with an S1 control (α = 0.05, corrected for multiple tests following Benjamini and Hochberg 1995). Comparisons are based on marginal, adjusted, values for the tested generations. Three categories are provided: equal direction (=), opposite directions (≠), and both unchanged. N represents the total viable pairwise combinations available for among-generation comparison

Significant (P < 0.001) directional effect deviating from 1:1 equal/ opposite (Chi-square, df = 1).
N in the BC1 generation is lower, as dominant loci with a dominant L. serriola allele will show all a band being either heterozygous or homozygous L. serriola.
No directional effect deviating from 1:1 equal/opposite (Chi-square, df = 1).
