Figure 2

Plot of the squared correlations (r2) versus distance in bp between sites for populations from New York (grey circles) and California (black squares) in the top panel, and Europe, clover (grey circles), and Europe, alfalfa (black squares), in the lower panel. Data from all four loci (two sequenced amplicons per locus) are included. The fitted curve of Hill and Weir [39] illustrating the expected decay of LD is shown for each population.
