Bayesian assignment of simulated purebred and hybrid individuals obtained by HYBRIDLAB , as implemented by NEWHYBRIDS . Pure molestus, pure pipiens and hybrid (F1, F2 and backcrosses with each parental line) simulated individuals were generated from the genotypes of Cx. pipiens specimens that displayed by NEWHYBRIDS a qi>0.90 of being pure molestus (N = 100) and pure pipiens (N = 11). Simulations were done using HYBRIDLAB  to produce 100 simulated individuals for each class. Each vertical line represents a simulated individual. Lines are partitioned in colours according to the probabilities of assignment to each class. A: probabilities were obtained for each of the six classes. B: the "hybrid" category is the sum of probabilities of assignment to each of the four hybrid classes originally simulated.
