Question

Quizplus · Accepted Answer

Injecting additional bicoid in the other end of the embryo would disrupt the normal gradient of bicoid protein and could result in the development of two heads instead of one. This is because bicoid protein plays a crucial role in establishing the anterior-posterior axis of the embryo, and an excess of it in one end could result in the development of extra anterior structures, such as a second head.
