—Recombination in chromosome 1 of melon (left) and chromosome 7 of cucumber (right). Correlation of gene density versus recombination rate in melon (a) and cucumber (b). Red spots represent the mean of the recombination rate on 100 separated bins with respect to gene density. Distribution of recombination rate along the chromosome in melon (windows of 500 kb) (c) and cucumber (windows of 100 kb) (d). The red line indicates cumulative recombination rate. The grey bars on top indicate TE-dense regions.
