  • Insertions and deletions are relative to the D. melanogaster HB transposon. Coordinates are from GenBank accession no. X01748.

  • a TIR, event occurs within the HB terminal inverted repeats; ORF, event occurs within the HB open reading frame.

  • b D. melanogaster does not possess homologous HB sequence.

  • c Deleted region replaced with 6-bp nonhomologous DNA.
