Correlation between the crossover rate and the current GC-content or the stationary GC-content (GC*), and correlations between human and chimp GC*.

Crossover rate: HAPMAP. Pearson's correlations (R2) are given for different window sizes, and different genomic regions (all non-coding sequences or introns and intergenic regions), for autosomes (A) and for the X chromosome. All correlations have a p-value <10−10, except (a) non-significant, (b) p-value = 3 10−5 and (c) p-value = 7 10−3.
