Figure 4. The structure of the 181-bp repeat sequences.

Yellow squares indicate exon 7 sequences not included in the repeat. Blue squares indicate sequences shared with exon7 and repeats in intron 7. Pink squares indicate intron7-specific sequences. Green squares indicate sequences conserved among the OnubOR5a,b genes. Red vertical lines show base substitutions. Black vertical line indicates a putative deletion in the last truncated repeat of the OnubOR8 gene.
