Description
Figure S1: The decay of linkage disequilibrium (LD) in: V. acerifolia, V. aestivalis, V. aestivalis var. aestivalis, V. champinii, V. cinerea, V. cinerea var. helleri, V. labrusca, V. riparia, V. rupestris, V. vinifera subsp. vinifera, V. vulpina. LD was estimated calculating the pairwise squared correlation based on genotypic allele counts (--r2 option in PLINK; Purcell et al. 2007) for all intrachromosomal SNP loci up to 500 kb. Each point represents the median r2 value and the mean physical distance from bins of 75 pairwise SNP comparisons. LD decay is rapid in all species considered. N: the number of individuals sampled to estimate LD; Bin width: the number of pairwise r2 values included in each bin; dotted black lines indicate r2= 0.2. Physical inter-marker distance is expressed as kilobase pairs (kb).
