^a Q₁ is the RPKM value at the first quartile. Q₁ is defined as the middle number between the smallest number and the median (i.e., the second quartile Q₂), if the data numbers (in this case RPKM values) are ordered from smallest to largest. The third quartile (Q₃) is the middle value between the median (Q₂) and the maximum (Max) value

^b Adjusted P-values from Wilcoxon signed-rank test, to test if Q₂ values (median) of genes located on the upper half of Chr 1 are significantly different from Q₂ values of genes located on the lower half. Values below 0.05 are considered significant
