Figure 3From: Bursts and horizontal evolution of DNA transposons in the speciation of pseudotetraploid salmonidsBursts of DNA transposon activity. Horizontal bars represent the duration of bursts of Tc1-like DNA transposon in Salmo salar, based on earliest and latest branching. The shaded areas indicate the approximate timing of the genome duplication event (left) and further speciation events [4] (right).Back to article page
