A heat map of pairwise marker distances in the JI2202 × JI2822 RILs. The colour coding of the heatmap (green to purple) is shown on the bottom right. The values for R, the fraction of recombinant inbred lines that have recombined the parental alleles, are shown for every 10th marker. A double-headed arrow indicates a translocation between LG III (chr5) and LG VI (chr1). On the right the χ2 value for the segregation ratio is plotted for all markers, where the expectation is a 1:1 segregation. The sign of the χ2 is positive for an excess of JI 2202 alleles and negative for an excess of JI 2822 alleles. The parallel lines at the base of the plot correspond to the values χ2 − 6.635, 0 and 6.635, representing the 1% confidence interval.
