Species: Danio rerio
The following phylogenetic tree shows the relationship between Danio rerio and a portion of other Danio and Devario species.
The phylogenetic relationships depicted above were inferred maximum likelihood analyses of 12S and 16S mtDNA. Numbers above branches are support values from Bayesian analysis and nonparametric bootstapping. Figure and analysis by: Parichy, DM. Evolution of danio pigment pattern development.
