Genome-wide recombination landscape in pollen. a Comparison of sliding window-based (window size 1 Mb, step size 50 kb) recombination landscapes in pollen and F₂ populations (P1250R1/R2), showing genome-wide consistencies but with 13 regional differences (1.1 ± 0.2 Mb) as indicated by horizontal lines in purple with p < 0.05 (i.e., p-values of Fisher’s exact test; Methods). Heterochromatic regions⁴⁴ are indicated by rectangles in light blue. b Correlation of genome-wide CO frequencies in pollen and F₂s (Correlation test, Pearson’s r 0.80~0.86, both p-value < 2.2e-16).
