Pattern of sequence conservation in the shavenbaby cis-regulatory region. Scheme of a multiple sequence alignment of the shavenbaby upstream region in 12 Drosophila species (bottom). Mel, D. melanogaster; sech, D. sechellia; sim, D. simulans; yak, D. yakuba; ere, D. erecta; ana, D. ananassae; per, D. persimilis; pse, D. pseudoobscura; wil, D. willistoni; moj, D. mojavensis; vir, D. virilis; gri, D. grimshawii. Empty boxes indicate the position of svb embryonic enhancers and triangles indicate coding regions. Z678, A8 and 7H are the ‘minimal’ versions of enhancers Z, A and 7, respectively. The pattern of sequence conservation is shown in grey (top). Sequence identity was calculated in 100 bp windows.
