Following statements are given regarding to the genes in Drosophila.
A. The anterior posterior compartment of each segment of drosophila is regulated by the expression of engrailed and wingless genes.
B. The gap genes are activated or repressed by the maternal effect genes, and are expressed in one or two broad domains along the anterior-posterior axis.
C. The transcription patterns of the anterior gap genes are initiated by the different concentrations of the Hunchback and Bicoid proteins.
D. The segment polarity genes encode proteins that are constituents of the delta-notch and Hedgehog signaling pathways.
E. After the segmental boundaries are set, the pair-rule and gap genes interact to regulate the homeotic selector genes, which specify the characteristic structures of each segment.
