Figure 3

Median-joining (MJ) network for ND4 putative mtDNA sequences from 141 individuals of Ae. aegypti from Southeast Asia. Note: Each circle represents a unique haplotype. Circle size is propotional to haplotype frequency and circle colour indicates the country of origin. The lengths of branches between haplotypes are proportional to the number of mutations. Numbers along branches indicate 3 or more mutational differences between the haplotypes. Δ refers to non-synonymous mutations with amino acid changes: [1] Valine to Isoleucine; [2] Proline to Serine; [3] Isoleucine to Valine; [4] Serine to Proline. As indicated by an arrow, the published mtDNA sequence corresponds to the clade 2 core sequence.
