Question

Quizplus · Accepted Answer

A neomorphic dominant mutation in the Antennapedia (Antp) gene of Drosophila causes the growth of a leg from the head region, a phenomenon called the Antennapedia phenotype. This mutation results in a change in the developmental fate of the cells in the head region, causing them to form leg structures instead of antennae.
