Average lengths in bp of simulated tract lengths for NCO and CO with 95% confidence intervals, which define the variation are listed. “NCO 2 Chtd” are tracts for NCO events with tracts on two chromatids within 3 kb of each other. NCO w/CO are tracts for NCOs within 3 kb of a CO event. Both of these types of events are pooled from all tetrad data.
