We have characterized mutations of the Abdominal-B gene of the bithorax complex of Drosophila. We conclude that the gene contains two distinct genetic elements: one has a morphogenetic role and acts in parasegments 10, 11, 12, and 13, while the other acts on parasegment 14 and has primarily or exclusively a regulatory function. Evidence indicates that the latter suppresses the activity of the morphogenetic element of Abd-B and of other genes responsible for the development of sclerotic plates… CONTINUE READING
