Phylogenetic trees for cyclins A (A) and D (B). Branching significance estimated in calculation of phylogenetic tree was supported by numerical values (the Shimodaira and Hasegava test and the aLRT χ2 test). Bifurcations resolved manually on the basis of literary data are indicated by asterisks (*). Inner branches for which atypical replacements were observed are highlighted in red.
