Specify a genetic distance value (in centiMorgans (cM)) to use for further breaking groups. If the genetic distance between two ordered markers in a linkage group exceeds this threshold, the group is broken into two groups between those markers.Note the following:
• One linkage group can be broken into multiple (>=2) linkage groups.
• A marker with a genetic distance greater than the specified value with both flanking markers is placed into a singleton group and dropped out of the analysis.
Check the Break linkage groups between markers with large ordered distances box to activate the Break linkage groups based on: field.
