Fig. 3.

The median joining network of Haemonchus contortus isotype-1 β-tubulin gene sequences generated in Network v.4.6.1. This network was built using 36 different isotype-1 β-tubulin gene haplotypes from eight populations. The size of each circle representing each haplotype is proportional to its frequency within the sequence dataset. The different coloured squares at the bottom represent each population. Colours in each circle show the frequency in each population. Small red dots represent median vectors. The red and blue text indicate E198A - benzimidazole (BZ) resistant haplotypes containing F200Y (TTC)/F167Y (TTC)/E198A (GCA) and F200Y- BZ resistant haplotypes containing F200Y (TAC)/F167Y (TTC)/E198A (GAA), respectively. BZ susceptible haplotypes are not marked. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
