Extent of linkage disequilibrium (LD) measured as the squared correlation of allele counts (y-axis), based on the maximum likelihood solution to the cubic equation. The x-axis shows inter marker distance in bp. LD estimates were sorted according to inter-marker distance, and divided into bins of 1000 estimates. Each point on the plot represents the mean R 2 and mean inter-marker distance of 1000 measurements
