• Values of k were calculated for scenario 1 (k1) and 2 (k2) (Figure A2B) using the formula in Figure A2C. The corrected fraction of GFP* conversions that are crossover associated (%COcorr) was calculated using Equation 4.

• a Because msh5Δ strains do not show crossover interference, k2 (calculated assuming complete interference) is not applicable.
