The numbers of sequences that are conserved between D. melanogaster (D. mel.) and D. pseudoobscura (D. ps.), and between these species and A. gambiae (A. gam.) are shown. ncRNA sequences include tRNAs, snRNAs, snoRNAs, and some unknown noncoding RNAs. Sequences that overlapped an exon were classified as exonic if they overlapped by at least 95%, and otherwise as “splice site.” % ibp indicates an average percentage of base pairs located within intron. Intronic sequences do not overlap any annotated exon.
