Relationship between transcription and recombination rates. (A) Mean recombination rate in cM/Mb (centimorgans per megabase) for genomic regions grouped according to the number of genes transcribed (FPKM > 0.1) within each 100-kb region. Spearman’s R = 0.168 (P = 1.5x10-9) based on non-overlaping 100-kb regions. (B) Mean recombination rate in cM/Mb for regions grouped according to the total region transcribed within each 100-kb region. R = 0.123 (P = 1.1x10-5). Error bars represent +/− 1 standard error.
