Correlation between relative class I and class II mobilome content. Panels a), b), and c) display the correlations between DNA transposons and LINE, LTR, and SINE transposons resulting from phylogenetic generalized least-squares regressions, respectively. Panels d) and e) illustrate the correlations based on a phylogenetic generalized least squares regression between LTR transposons and LINE and SINE transposons, respectively. Panel f) presents the correlation based on a phylogenetic generalized least-squares regression between LINE and SINE transposons.
