Phylogenetic analysis of animal Mcm8 and Mcm9. This analysis was conducted to investigate the diversification and branching position of the Drosophila Mcm8 proteins as Drosophila is the only lineage with an Mcm8 but with no Mcm9. The analysis shows that the Drosophila Mcm8 proteins are highly divergent. The phylogeny shown is a calculated from an amino acid alignment of 43 sequences and 366 characters. The tree topology shown was calculated using PHYML methods. Mcm8 paralogues are shown in blue and Mcm9 paralogues in pink. The orange coloured block indicates the relationship of Drosophila spp. Mcm8 with Mcm8 sequences from other animals plus additional outgroups. Numbers on nodes indicate the ML bootstraps and Bayesian posterior probabilities (bootstrap values below 50% and posterior probabilities below 0.90 are not shown). The phylogeny is shown as rooted on the Mcm9 paralogue.
