(A) Neighbor-joining tree based on pair-wise F_ST values between populations of Anopheles gambiae sensu stricto estimated using the ND5 mitochondrial gene. To better distinguish the M and S populations, M-form populations are written in italics. Triangles indicate populations that have been split into an S-form population and an M-form population. (B) Neighbor-joining tree based on pair-wise F_ST values between populations of Anopheles gambiae estimated using the ITS sequence data. NJ trees are not intended to infer phylogenetic relationships but rather to show clusters of F_ST values. Taxa are labeled as in Table 1.
