  1. a Biogeographic domains are as defined in Figure 1: SA, Sahelian Area; TD, Tropical Dry; AH, Adamaoua Highlands; WH, Western Highlands; CP, Central Plateau; AC, Atlantic Coast.
  2. b Karyotypes are encoded according to the sequence of inversions on chromosome-2, each digit corresponding to the observed karyotype for inversions 2Rj, b, c, d, u, k and 2La, respectively.
  3. 1/Σpi2: chromosomal diversity index, where pi is the frequency each karyotype in the population [72].
  4. Distribution and frequency of chromosome-2 karyotypes observed in the M and S molecular forms of An. gambiae in Cameroon.
