Figure 2

Unrooted distance neighbor-joining tree showing the phylogeny of α-esterases from the genome of Culex pipiens quinquefasciatus in relation to those from Aedes aegypti (initiated with ‘AAEL’) and Anopheles gambiae (initiated with ‘agCP’ or ‘ebiP’). The percentage of bootstrap confidence values greater than 70% (1000 replicates) is shown at the nodes.
