Figure 2From: R-spondins are involved in the ovarian differentiation in a teleost, medaka (Oryzias latipes)Phylogenetic tree of Rspo family proteins of vertebrates was constructed by using mouse thrombospondin-1 as an outgroup. Values on the tree represent bootstrap scores of 1000 trials, indicating the credibility of each branch. Branch lengths are proportional to the number of amino acid changes on the branch.
