Fig. 3. Haplotypes observed in the Xcup15 region of cultivated and wild sorghum excluding locus 9–10b. Numbers across the top of the figure indicate the site coordinate within the BAC sequence (bp), and the shaded area denotes the position of the derived fixed nucleotide difference between cultivated and wild sorghum accessions. Dots indicate sequence identity to reference sequence. Segregating nucleotide sites are shown only for accessions with no missing data. Insertion–deletion polymorphisms were excluded from the analysis. Mutations unique to S. propinquum are not shown.
