The association between recombination and genes.

<p>(<b>a</b>) Distribution of recombination events in relation to distance to the closest gene. The large bar at position 0 represents the number of events overlapping with genes. (<b>b</b>) Density of CO events in different sequence categories of genes, and in intergenic DNA. <b>c</b>) Density of NCO events in different sequence categories of genes, and in intergenic DNA.
