Transposon DNA methylation from mouse. Transposon families above a threshold of 2% genomic content are shown. DNA methylation is calculated from biological replicates of mouse tissues with coverage ranging from 0.0025× to 0.016×. Transposon families with significant differences are shown with ANOVA followed by Tukey's multiple comparison test. (*) P ≤ 0.05, (**) P ≤ 0.01, (****) P ≤ 0.0001.
