Bayesian assignment of multilocus genotypes of simulated purebred and hybrid individuals (a) and real adults (N=421) from three sympatric populations (b–d) using the software NEWHYBRIDS. Each line represents an individual's posterior probability of assignment (qi) to each of six genealogical classes including: purebred E. aggregata, purebred E. rubida and four hybrid classes (F1, F2, backcrosses towards each parent (Bx aggregata, Bx rubida)). Simulated individuals for each of the six classes were generated using reference genotypes and HYBRIDLAB. Arrows indicate individuals assigned as purebred E. rubida using the software STRUCTURE.
