Fig. 2. Chromosomal patterns of gene flow from western sylvestris into table grapes generating Alpine wine grapes.
a Dots represent adjusted fd values in 100 Kb windows of non-repetitive DNA. Lines represent cubic smoothing splines of the values. b Diagram of 100 Kb chromosomal windows (in red) that show phylogenetic tree topologies with shorter genetic distance between Alpine wine grapes and western sylvestris than between Alpine wine grapes and any other cultivated group. Red triangles in a and constricted regions in b indicate the location of centromeric repeats. Source data are provided as a Source Data file.
