Sex-chromosome biased patterns of corrected TE densities in primates. Relative densities of Alus (A) and L1s (B), after accounting for regional variation in local genome landscape features, are compared among the X, Y, and autosomes (A) for each branch in the primate phylogeny. Statistically significant differences are indicated with inequality symbols (>), whereas insignificant differences are indicated with equality symbols (≥).
