Phylogenetic tree of Chromis multilineata haplotypes. The 50% majority-rule consensus tree from the Bayesian analysis of Chromis multilineata haplotypes. The alternative method of maximum parsimony resulted in almost identical topology. Numbers beside branches correspond to posterior probabilities estimated using the Bayesian approach, and numbers below branches refer to the bootstrap support calculated from the maximum likelihood analysis of 500 sequence replicates assuming model parameters values estimated from Modeltest (see methods). Color code as follows: red, Caribbean; blue, South Atlantic (Brazil + mid-Atlantic Islands); yellow, Africa (Cape Verde + Sao Tome). The branch leading to outgroup was reduced by 50%. Arrows indicate haplotypes shared by the South Atlantic and the Caribbean.
