Primers were designed to PCR-amplify genes and regions flanking the insertion sequence (Additional file 1: Table S 10) such that a difference in size of the amplified product reflects the presence of the insertion element (1362 bp).
That is to say, a difference in size existed in the Primary Universe, and that this difference had a Cause.
Due to a difference in sample sizes between abiotic and biotic data sets, we also conducted nonparametric bootstrapping to assess differences in QTL effect sizes.
