Regulating Growth and Development

Homology Between Drosophila Antenna & Leg Segments

Insects have evolved specialized structures by variation on a theme. Not only can gene manipulations and mutations produce a leg on the head of an insect in place of an antenna, but an antenna can grow in place of a leg.

Close examination of thousands of partial transformations of antennae to leg reveals a homology between the segments of the leg and segments of the antennae (see diagram). In the development of an appendage, one set of genes…
