L1HS mappability score distributions. We calculated the percent of each element’s sequence with unique mappability scores and then generated a histogram from those percentages. In (a), the pink distribution is the 1,542 not putatively active elements and the blue distribution is the 144 putatively active elements. Using a permutation test, the means of these distributions are significantly different (p = 2.2e-16). In (b), the blue distribution is made of the L1HS-Ta elements and the purple distribution is made of the L1HS-preTa elements. The means of these distributions are also significantly different (p = 2.491e-06) when using a permutation test
