From: Mollusc genomes reveal variability in patterns of LTR-retrotransposons dynamics
Phylogenetic relationships of Copia retrotransposons. The tree is based on Neighbor-Joining analysis of RT/RNaseH domain amino acid sequences. The Copia families from molluscs are indicated in color and arc of different colors indicate major clades. The number of mollusc species covered by each clade in the phylogeny is given into brackets. Node statistical support values (> 70%) come from non-parametric bootstrapping using 100 replicates
