Figure 2From: Two Frequenins in Drosophila: unveiling the evolutionary history of an unusual Neuronal Calcium Sensor (NCS) duplicationPhylogenetic tree of insect frq homologuous genes. Bayesian phylogeny of insect homologues based on substitutions at synonymous positions. Arrows indicate the age of the Frq1-Frq2 duplication and of the common ancestor of Drosophila and Ceratitis Frequenins. The 95% high posterior density intervals of node ages are depicted in grey. Coloured shaded boxes denote the frq1 and frq2 subtrees. The ω values estimated in the ML analysis are also shown. Scale is in My.Back to article page
