How a single Hox gene (Ultrabithorax) can specify two different morphologies ?

By | April 20, 2021

Bithorax complex in Drosophila consists of three homeodomain encoding proteins : Ultrabithorax (Ubx), abdominal-A (abd-A) and Abdominal-B (Abd-B). The function of these bithorax genes is to pattern entire abdomen ( A1-A9 segments ) and a part of third thoracic segment ,which happens to be their normal expression domain in embryos. These Hox proteins are expressed… Read More »
