Additional file 8: of 100 million years of multigene family evolution: origin and evolution of the avian MHC class IIB

Phylogenetic relationships based on the ten sites identified to reflect duplication history using Saguaro [29]. Bayesian posterior probabilities are provided for all nodes with support >50 and for the two main clusters deflecting DAB1 and DAB2, respectively. Redundant sequences within orders were removed prior to phylogenetic reconstruction. The consensus tree taking into account all compatible branches is shown. (PDF 1058 kb)
