Figure 1: Multiple alignments of the amino acid sequences downstream of the bcd homeodomain in blowflies. The sequences–70 amino acids downstream of the bcd homeodomain in 12 blowfly species were aligned to the 73 amino acid sequence of M. domestica (AJ297854). All 12 blowfly species lack the three serine residues present in M. domestica. Other serine residues are also deleted from around the distinct serine-rich region. All blowfly sequences were represented without being accountant for intraspecific variation.
