Figure 1

Average linkage disequilibrium (LD) decay rate in euchromatic and heterochromatic regions of the soybean genome. The mean LD decay rate was estimated as squared correlation coefficient (r ²) using all pairs of SNPs located within 10 Mb of physical distance in euchromatic (red) and heterochromatic (black) regions in a population of 309 soybean germplasm accessions. The dashed line in grey indicates the position where r ² dropped to half of its maximum value.
