Estimates of mean mtDNA sequence divergence within sampled An. melas populations and clusters, and An. gambiae populations. The rate variation among sites was modeled with a gamma distribution (shape parameter = 6). Codon positions included were 1st+2nd+3rd+noncoding. There were a total of 1161 bp positions in the final dataset.
