Di-, tri-, and tetra-nucleotide motifs were rank-ordered along the x-axis according to their correlation with GC content (dotted lines). Their correlation with the average local recombination rate followed a similar pattern (solid lines). This result suggests that GC content instead of specific nucleotide sequences is the most parsimonious explanation of local recombination rate in honey bees. Similar conclusions can be drawn for the variability of recombination rate (dashed lines).
