Evolutionary relationships among vertebrate β-like globin genes using a 50% majority rule consensus phylogram from an analysis using Bayesian inference. The tree was constructed using mixed models of evolution for each codon position (see methods) and estimated base frequencies in an unlinked analysis using MrBayes (v. 3.1.2). Numbers adjacent to branches refer to % posterior probabilities. GenBank accession numbers for sequences are: Fat-tailed Dunnart (Sminthopsis crassicaudata) β [Z69592], ε [Z48632], ω [AY014770]; Stripe-faced Dunnart (S. macroura) β, ε [AC148754]; Virginian Opossum (Didelphis virginiana) β [J03643], ε [J03642]; Brazilian Opossum (Monodelphis domestica) β [XM_001365299], ε [XM_001364448], ω [XM_001364828]; Tammar Wallaby (Macropus eugenii) β [AY450928], ε [AY450927], ω [AY014769]; African clawed frog (Xenopus laevis) larval β I [NM_001086273], larval βII [NM_001088028]; Western clawed frog (X. tropicalis) β [NM_203528], larval ε1 [NM_001016495]; Chicken (Gallus gallus) β (β^A) [NM_205489], ε [NM_001004390], γ (β^A) [NM_001031489]; Duck (Cairina moschata) β [J00926], ε [X15740]; Human (Homo sapiens) β [NM_000518], γ [BC130459], ε [NM_005330]; Mouse (Mus musculus) β (β1) [NM_008220], γ (β h0) [NW_001030869], ε (ε^y) [M26897]; Goat (Capra hirus)β (β^A) [DQ350619], ε (ε^I) [X01912], γ [M15388]; Rabbit (Oryctolagus cuniculus) β, γ, ε [M18818]; Echidna (Tachyglossus aculeatus) β [L23800]; Pufferfish (Fugu rubripes) β [AY170464]; Zebrafish (Danio rerio) ε1 [NM_001103130]; Platypus β, ε [AC192436], ω [AC203513].
