Which of the Following is a Segmentation Gene Discovered Along

Question

Which of the following is a segmentation gene discovered along the anterior-posterior axis?
A) Gap genes
B) Pair-rule genes
C) Segment polarity genes
D) Gap genes and Pair-rule genes
E) All of these are correct.

Accepted Answer

All of these genes (Gap genes, Pair-rule genes, Segment polarity genes) play crucial roles in the segmentation of the anterior-posterior axis during embryonic development in Drosophila and other segmented organisms. Each type of gene functions at a different level of the segmentation hierarchy to establish the segmented body plan.
