For each subinterval, statistically significant relationships among rates of recombination in the A632/LC (A), Oh43/LC (O), and W64A/LC (W) genetic backgrounds are shown. The P values associated with χ2 homogeneity tests are provided in parenthesis. In a given subinterval, rates of recombination are indicated as being not distinguishable (≃) if P > 0.05.
The distribution of breakpoints across the entire a1–sh2 interval in the Oh43/LC background differed significantly from the distributions in both the A632/LC (P = 0.013) and W64A/LC (P = 0.0008) backgrounds.
Because no recombinant breakpoints mapped to this interval in either background, rates of recombination could not be compared. ND, not determined.
