Fig. 2: Bayesian clustering analysis by STRUCTURE of Aedes aegypti. The multilocus genotype of each individual is represented by a bar. Clusters (K) are represented by different colours and the proportion of each colour in the bar represents the probability of assignment (Q) to each cluster. (A) Analysis of 55 American populations (N = 2,224) with eight loci, sorted by locations and countries. (B) Analysis of the 33 populations (N = 1,409) that were assigned to the blue cluster in (A). (C) Analysis of 15 populations (N = 629) that were selected from (B). (D) Analysis of the eight samples (N = 348) genotyped for 13 loci in this study. These samples are framed by the white dashed line in A, B and C.
