Pairwise comparison of SNP haplotypes for eight sorghum accessions. Each main numbered horizontal plot represents one accession. Its seven minor plots represent pairwise genotype comparisons of called SNPs with those in the other seven accessions; in the upper panel only matches of the reference homozygote and in the lower only those of the alternative homozygote are shown. The color coding indicates windows of 50 SNPs with at least 30, 50, or 70% of genotypes in common between the two accessions (coded as S in the legend). Strips at plot bases show correspondence of the SNP windows with the physical map. Accessions 1-8 are BTx623, BTx430, P898012, Segaolane, SC35, SC265, PI653737 (S. propinquum), and 12-26 (S. bicolor ssp. verticilliflorum). Scale at bottom indicates physical positions of SNPs on chromosome. All chromosome plots appear in Figures S9-S18.
