Unrooted Neighbor-joining tree of full-length Pokey elements from the Daphnia genome. The 27 elements containing putative transposase genes and less than 5% ambiguous bases, and the consensus rDNA element (Con-rPokey) are included in the tree. The elements form two well-supported clusters that correspond to the inverted terminal repeat (ITR)1 and ITR2 sequences (Figure 1C). All positions containing gaps and missing data were eliminated in pairwise comparisons. Bootstrap values greater than 70 are indicated at the nodes of the tree.
