Average linkage disequilibrium plotted against distance between SNPs. Average linkage disequilibrium (solid line) measured as r ² and the 5th and 95th percentiles (dashed lines) plotted against the average of the distance bin range (Mb). To enable a clear presentation of results, distances between SNP pairs were divided into three distance ranges: (i) 0 to 2 Mb, (ii) 2 to 5 Mb and (iii) 5 to 50 Mb. Distance bins of 0.05, 0.20 and 5.00 Mb were used for classes (i), (ii) and (iii), respectively, and average r ² values pooled over autosomes for each bin were plotted against physical distance
