A Plots of Runs (Chromosome) tab is shown below:The Plots of Runs (Chromosome) tab is created for each value of the Chromosome variable selected in the process dialog and contains the following elements:The y -axis of this plot represents the Run Length for each run and the x -axis has the chromosome location. If you zoom in far enough (using JMPs tool), you can see what looks like a point on the plot is actually made up of points for each SNP included in the run all with the same y -axis value. This number of points is the same as the Run Length.The Data Filter on the right can be used to restrict the display to run lengths in a certain range.You can select a run or individual SNP points then click on the button to bring up a cell plot view of the offspring genotypes at the selected SNPs. An example of this plot (for the run circled in the figure above) is shown below:
