RNA-Mediated Gene Duplication and Retroposons: Retrogenes, LINEs, SINEs, and Sequence Specificity

Figure 4

Relationship between the number of SINE/LINE pairs and the number of LINEs in each clade. The vertical axis shows the number of SINEs with a LINE tail [34]. The horizontal axis shows the number of LINEs belonging to each clade. The linear regression line, determined by the least squares approach, is shown, except for L1. indicates the coefficient of determination. CR1-clade LINEs (580 families) and L2-clade LINEs (10 families) were summed due to their confusing nomenclature.
