Frequency distribution of admixture coefficients (Q1) of multilocus genotypes of simulated parental and hybrid individuals (a–c), and adult plants at each of three sites: (d) Bendoura, (e) Duck Flat and (f) Norongo. Adult plant assignment based on the following thresholds: Q1>0.9 as E. aggregata, Q1<0.1 as E. rubida and 0.1 ⩽Q1 ⩽ 0.9 as hybrids.
