WebSep 1, 1995 · In Drosophila, the Hox gene Ultrabithorax (Ubx) specifies the development of two different metameres--parasegment 5, which is entirely thoracic, and parasegment 6, which includes most of the first abdominal segment. Here we investigate how a single Hox gene can specify two such different morphologies. We show that, in the early embryo, … WebThe bithorax gene complex in Drosophila contains a minimum of eight genes that seem to code for substances controlling levels of thoracic and abdominal development.
