From: A family history of DUX4: phylogenetic analysis of DUXA, B, C and Duxbl reveals the ancestral DUXgene

Figure 9

Homeobox duplication in DUX genes. Hypothetical scenario of homeobox duplication at the sDUX locus. As an illustrative example, the two tandem wallaby sDUX copies are shown with all sizes and distances to scale. A deletion could join the two genes leaving a single intact DUX ancestral gene. New intron redrawn at 1/8th size (intron scale). Subsequent splicing changes could result in intron gain. Mouse Duxbl is shown for comparison.
