Which developmental consequence result when imaginal discs experience localized Hox gene repression during pupation in Drosophila?

A)Segmental identity transformations occur
B)Apoptosis limits the adult structure's size
C)Reduced regenerative capacity is exhibited
D)Increased susceptibility to bacterial infection

💡 Explanation

When localized Hox gene repression occurs in imaginal discs during Drosophila pupation, specific segmental identity transformations happen, because Hox genes precisely control the development of body segments by regulating downstream target genes relevant for regional development. Therefore, changes to the body plan's segmentation results, rather than effects to size, regeneration, or immune function, each requiring respective impacts on cell cycle control, stem cell activity or, immune cell development.
