Expression level fold-change for significant SNP-probe <i>cis</i>- associations shared by pairs of populations.

<p>Shown are plots of the absolute value of expression level fold-change between median expression levels of homozygote classes for significant associations (permutation threshold 0.01) for each pairwise combination of populations. Within a panel, deviating from the 1 to 1 line (lower left to upper right) indicates differences in expression level fold-change (effect size) on log₂ scale in the two populations being compared.
