Anopheles gambiae has more unidirectional piRNA clusters than does D. melanogaster. Spider chart depicting bias (>75 % of piRNAs map to one genomic strand) (a, c) or (>90 % of piRNAs map to one genomic strand) (b, d) for clusters per chromosomal arm as well as all clusters combined. The percentage of clusters on each arm (or total) is displayed for either bias or no bias in An. gambiae (a, b) and D. melanogaster (c, d)
