Genomic arrangement of Xmr, Xlr and Sly. Sly exons 1–4 are homologous to Xmr exons 1–4. Sly exons 5–6 represent an internal duplication of exons 3–4. Sly exons 7–10 are homologous to Xlr exons 5–8. There are LINE elements at the borders of each section, suggesting that Sly was formed by recombination between LINE repeats. 
indicates the location and orientation of these LINE elements.
