HG38 chr1: Histogram (probability distribution in bins of Δx = 0.02) of relative occurrences of k-mer pairs vs x for different values of k (4 to 10). a inverse pairs; plotted range is x < 0.3, above which the histogram values are negligibly small. b random pairs for full x range; c Reverse pairs for full x range
