Figure 4 Distribution of the percent of reads that are identical to the P. vaginatum reference genome at heterozygous loci in four coarse-textured P. vaginatum samples representing the most common diploid hybrid genotype (coarse_03, represented by DG076) (A ) and the three triploid genotypes: coarse_01 (accession DG117) (B) , coarse_02 (accession DG107) (C ) and coarse_04 (accession DG120) (D) . Bars in the top right corner indicate the number of haploid subgenomes from P. vaginatum (black) or an unidentified progenitor species (grey).
