2C DCOs mean two COs use the same non-sister chromatids; 3C DCOs mean two COs share one chromatid; 4C DCOs mean two COs use the different pair of non-sister chromatids.
Chi-Square test of goodness-of-fit was performed for each ratio, and no significant deviation from the 1:2:1 ratio was detected. The significant p value was corrected by the fdr method.
