FIGURE 3.

Impact of domestication and breeding on cranberry (Vaccinium macrocarpon Ait.) genetic diversity. (A) Density plots for F_ST values among all subgroup combinations. Colors are based on meaningful subgroup comparisons in the context of the cranberry domestication/breeding history (step 1 in red, step 2 in green, step 3a in blue, and step 3b in purple; non-categorized comparisons are displayed in yellow and as step *). Red vertical lines correspond to F_ST 95th percentiles (significant thresholds) obtained from permutation analysis on each subgroup comparison; numbers after the red line correspond to the number of significant F_ST values on each subgroup comparison. (B) Genomic regions with different levels of reduction of diversity (ROD = 0, ROD >0 and ≤0.2, ROD ≥0.8 and <1, and ROD = 1), organized according with A.
