Figure 4.
Gene and SNP distribution. To obtain the chromosomal distribution of genes, expressed genes, genes showing expression variation, and SNPs, we scanned each of the 20 soybean chromosomes by 1 mb sliding windows with 0.1 mb steps. SNP counts per 1 mb window are shown on the primary Y-axis and gene counts are displayed on the secondary Y-axis. The X-axis represents the chromosome length in mb.
