Assignment of An. gambiae karyotypes by multilocus genetic clustering. Genetic cluster analysis using STRUCTURE based on chromosome-2 karyotypes of the M and S form of An. gambiae in Cameroon. Each individual mosquito is represented by a thin horizontal line divided into K = 3 (most likely value of K) coloured segments that represent the individual's estimated membership fraction to each of the K = 3 clusters. A. Output based on chromosomal inversions stratified by decreasing latitude of the specimen's sampling locality (top = North to bottom = South); biogeographic domains are given on the left (cf. Figure 1). B. Same as in A, with specimens sorted according to their molecular form status. A black line separates specimens of the S (above) and M (below) molecular forms and within each form, specimens are sorted by decreasing latitude of the collection locality.
