Fig. 2From: Mapping freshwater snails in north-western Angola: distribution, identity and molecular diversity of medically important taxaMaximum Likelihood tree for Bulinus globosus and B. angolensis based on cox1 sequences. Maximum likelihood tree of a 613Ā bp fragment of the cytochrome c oxidase subunit 1 (cox1) gene for B. globosus and B. angolensis collected in this study, with additional previously published sequences [13]. B. forskalii was selected as the outgroup. Numbers at the nodes indicate bootstrap support (1000 pseudoreplications). The scale-bar indicates substitutions per nucleotide siteBack to article page
