Figure 4.

Structural variation within three common transposable elements: (a) jockey; (b) pogo; (c) roo. Multiple alignments generated from each respective family were used to approximate genomic variation. Each position along the length of the multiple alignment (x-axis) was measured for the presence of a nucleotide. The percentage of elements within an alignment that contained the nucleotide was determined and is indicated along the y-axis. A schematic drawing representing a jockey, pogo, or roo element is shown directly below each panel; coding regions are indicated by light-gray boxes and repeats (pogo and roo) are represented by black boxes.
