Fig. 3 Diversity within the populations of the A and B sets of the hierarchical, open-ended population enrichment (HOPE) maize breeding system. Distance between every two plants in a population was determined by the complement to the simple matching coefficient (the number of bands for which the plants did not get the same score divided by the total number of bands); population diversity is the mean of all pairwise distances. Standard error is given for each diversity estimate
