The top panels show the ratio of CENH3 ChIP-Seq reads divided by input control reads. ChIP-Seq and control reactions were performed in duplicates, which are shown in purple (Rep1) and orange (Rep2). The bottom panels show the chromosomal positions of RLG_Cereba (blue) and RLG_Quinta (red) retrotransposons (x-axis) and their insertion age (y-axis). The youngest retrotransposon insertions are generally found in the functional centromeres. Retrotransposon insertions on chromosomes 1A, 4A, 6A and 7A indicate that parts of the functional centromeres were moved at different evolutionary time points. The observed patterns can be explained by large-scale inversions that moved parts of centromeres (indicated by two-headed arrows, with y positions indicating the approximate time of the inversion event).
