Heat map showing a matrix of pair-wise recombination values for SFPs and microsatellite markers assayed on 148 RILs. Pair-wise comparisons between markers were used to assign recombination scores, which are plotted as a heat map matrix of all markers (top to bottom) against all markers (left to right). Lowest recombination scores, suggesting marker linkage, are indicated by red boxes, while blue boxes indicate high recombination scores, suggesting no linkage. The 599 SFP and 38 microsatellite markers are ordered by their physical location in the Col-0 genomic sequence; heavy lines demarcate the five linkage groups. (Supplemental Fig. 5a shows a high resolution version of this figure, including marker details.)
