D) morphogens
E) inducers

Question

Quizplus · Accepted Answer

Segmentation genes, specifically the gap genes and pair-rule genes, establish the basic subdivisions along the anterior-posterior axis of the Drosophila embryo. Homeotic genes are involved in determining the identity and differentiation of specific body segments, while egg-polarity genes and morphogens play roles in establishing the dorsal-ventral axis. Inducers refer to molecules that elicit a certain response in a neighboring cell, but they are not directly involved in axis formation in Drosophila embryos.
