Figure 2.

Alignments of the deduced head Hox protein sequences. Hexapeptide + variable region and homeodomain sequences are aligned for four insect species and the crustaceans A. franciscana and P. scaber (some sequences were not available). All sequences are compared with their Drosophila counterparts. Dashes indicate sequence identity, breaches in the sequences indicate introduced gaps. Species are indicated in the first column: Dm, Drosophila melanogaster; Of, Oncopeltus fasciatus; Ad, Acheta domestica; Td, Thermobia domestica; Ps, P. scaber; Af, A. franciscana. Gene names are indicated in the second column: LAB, labial; PB, proboscipedia; DFD, Deformed.
