  • Columns are D. melanogaster (Mel) aligned with HB, D. simulans (Sim) with HB, and D. melanogaster with D. simulans (Mel × Sim) HB-like regions.

  • a HB-like sequence common to both species (1208 bp).

  • b HB open reading frame (GenBank HB coordinates 575–1021) only; melanogaster contains only 415 bp of the ORF.

  • c D.simulans insertion aligned to entire HB element (1572 bp).

  • d D. melanogaster and D. simulans homologous sequence outside HB-like element (987 bp).
