Quizplus · Accepted Answer

Maternal effect genes are genes that are transcribed and translated in the mother and then deposited in the egg. Bicoid is a Drosophila maternal effect gene that is responsible for the formation of the anterior-posterior axis of the embryo. Hunchback, Antennapedia, and Bithorax are all segmentation genes, but they are not maternal effect genes. Shh is a gene found in mammals, not in Drosophila.
