We accepted all individuals as hybrids that were identified in at least one of two corresponding datasets (combinations A and B), by at least one program (combinations C and D) and by at least one program in at least one of two corresponding datasets (combination E). Datasets: L: local sets (n = 100), E: enlarged sets (n = 100), L+E: combined evidence from corresponding local and enlarged sets; Discrepant between sets: individuals identified as hybrids in only one of two corresponding datasets; Discrepant between programs: individuals identified as hybrids with only one of the two programs; Disc true Hyb: percentage of true hybrids among discrepant individuals in the line above; N Hyb obs. per set/pair sets: range of observed numbers of hybrids in 100 datasets or pairs of corresponding datasets. The true number of hybrids per set was 60. We disregarded the 20,000 additional purebred individuals comprised in the enlarged datasets exclusively for the calculation of efficiencies, accuracies and numbers of discrepant individuals. Only six of these individuals were misclassified as hybrids in combination C.
