Question

Quizplus · Accepted Answer

The bicoid gene of Drosophila determines the formation of the anterior-posterior axis of the embryo by producing a protein that is concentrated at the anterior end of the egg during early embryonic development. This protein then acts as a transcription factor to regulate the expression of genes involved in establishing the body plan along this axis.
