The members of the evolutionarily conserved Hox-gene complex, termed Hox genes, are required for specifying segmental identity during embryogenesis in various animal phyla. The Hox3 genes of winged insects have lost this ancestral function and are required for the development of extraembryonic epithelia, which do not contribute to any larval structure. Higher flies (Cyclorrhapha) such as Drosophila melanogaster contain Hox3 genes of two types, the zerknüllt type and the bicoid type. The zerkn… CONTINUE READING
