Sliding-window analyses across the AZFa-HERV alignment. Beneath the schematic alignment of the proximal and distal AZFa-HERVs (with the inserted L1 material excised) are sliding-window analyses showing how various sequence measures vary across the alignment. These statistics represent the mean of these values across all three pairwise comparisons. The three measures applied are: the orthologous sequence divergence, the concerted index (CI) and the directionality index (DI), where the CI is greater than 0.5 (see text for details).
