* depending on linkage this karyotype can be assigned to either SAVANNA or MOPTI
** depending on linkage this karyotype can belong either to SAVANNA or be considered as a hybrid MOPTI/SAVANNA
Assignment of karyotypes observed in Burkina Faso according to three classification criteria: the recorded rDNA IGS state (Molecular Form), the multi-locus genetic clustering approach implemented in the software STRUCTURE, without prior assignment to a given population (Clusters 1 and 2), and the chromosomal form status according to [31]. The non-Linnean nomenclature FOREST, MOPTI, and SAVANNA defines groups of karyotypes (i.e. chromosomal forms) restoring Hardy-Weinberg equilibrium of chromosomal inversion markers in field populations of An. gambiae s.s., with particular reference to Mali (for more details, see [31]). The table presents the frequency of observed karyotypes falling in each category.
