Meta-analysis of genome-wide association studies of genome-wide recombination rates. The subplots are Manhattan plots of the negative logarithm of the p-value of association against genomic position, separately for females and males. Alternating colours correspond to chromosomes 1 to 18. Line 7 was excluded from the analysis because of its small number of dams and sires. The dashed red line shows a conventional genome-wide significance threshold of 5 × 10⁻⁸
