Fig. 3From: Analysis of the erythropoietin of a Tibetan Plateau schizothoracine fish (Gymnocypris dobula) reveals enhanced cytoprotection function in hypoxic environmentsEvolutionary relationships of the EPOs. The phylogenetic tree was constructed using the ML method, as described in the Methods. The calculated d N/d S (ω) values (in italics) and bootstrap values are shown in each branch. The branches with ω values ≥ 1.0 are shown in bold. The Tibetan Plateau schizothoracine G. dobula assigned to the foreground is highlighted by a red solid rectangleBack to article page
