From: The globin gene family of the cephalochordate amphioxus: implications for chordate globin evolution
Bayesian phylogenetic reconstruction reveals affiliations and possible orthologous relationships of B. floridae globin variants (bold face). Support values at branches are posterior probabilities and bootstrap percentages (> 40) of maximum likelihood analysis. Characteristic intron positions in the amphioxus globins are indicated and in some cases confirm monophyletic clades of BflGb paralogs. Species abbreviations are listed in the Material and Methods section.
