Early Duplication of a Single MHC IIB Locus Prior to the Passerine Radiations
Fig 1
Maximum likelihood tree of MHC IIB variants (248 bp) in seven species of Corvidae.
Four lineages (L1-L4) that contained four different genera clustered with > 75% bootstrap support (blue highlight). Pertinent bootstrap values are in parentheses. Cobr = American crow; Coco = carrion crow; Coma = jungle crow; Cofr = Asian rook; Gagl = Eurasian jay; Pipi = Eurasian magpie; Cycy = Azure-winged magpie. Red branches indicate > 70% bootstrap support. Scale bar in center indicates substitutions/site.
