Table S1. Summary of parental blocks from the intermediate files of ‘parent1.abxaa.5snps.blocks’, ‘parent2.aaxab.5snps.blocks’, ‘parent1.long.haplotype’ and ‘parent2.long.haplotype’, created by findGCO. Table S2. The number of SNPs contained in the long parental haplotypes from the intermediate files of ‘parent1.long. Haplotype’ and ‘parent2.long.haplotype’ created by findGCO. Table S3. Distribution of the number of gene conversion events detected in each of the 10 progeny and inherited from the male parent based on the reference genome sequences. Figure S1. CO patterns identified in each progeny on all chromosomes in the female parent P. deltoides. Figure S2. CO patterns identified in each progeny on all chromosomes in the male parent P. simonii.
