Bayesian cluster analysis conducted by STRUCTURE . Columns correspond to the multilocus genotype of each individual, partitioned in two colours representing the probability of ancestry (qi) to each cluster. Red: cluster 1 (molestus); blue: cluster 2 (pipiens). Individuals were ordered according to their genotype at the CQ11FL locus. Dashed lines indicate the qi threshold used to determine admixed individuals (see Methods). A: analysis performed with 13 loci; B: analysis performed without locus CQ11. Arrows indicate individuals with different assignment between analyses.
