Evidence for recombination event between simultaneously active Perissodactyla L1 families. Both trees were constructed using the maximum-likelihood method with the HKY + G model of a region both upstream and downstream of the estimated breakpoint of recombination. The sequences included in each alignment of ORF2 used to construct each tree are shown within the blue boxes. Bootstrap values out of 1000 replicates are shown at each node
