Figure 1.
Computational analysis pipeline for the identification of gene duplicates retained from whole-genome duplication in five teleost fish genomes. Synteny and phylogenetic analyses provide independent lines of evidence for origin by WGD. The level of support in the synteny and phylogenetic analyses was used to categorize WGD-duplicates. Duplicates of “high confidence” map to sister chromosome regions of shared ancestry and have tree topologies consistent with an origin by WGD.
