Levels of LD in swept and genome-wide regions in Medicago truncatula populations. We estimated average r² and D′ measures of LD in swept regions and genome-wide regions of the same length, in both M. truncatula populations. (A) Correlation of average genome-wide LD between the FW and C populations (the dotted lines show the linear regressions). (B) comparison of average LD in swept and genome-wide regions of the same length in the FW population, and in the C population (C). (D) For the FW population, comparison of genome-wide LD with LD in regions swept in the C population. (E) For the C population, comparison of genome-wide LD with LD in regions swept in the FW population. In (B)–(E), the solid line indicates the section of equal average LD.
