Which developmental consequence arises when imaginal disc differentiation is blocked during Drosophila pupation?

💡 Explanation

When imaginal disc differentiation is blocked, specific morphogenetic programs are disrupted because cells cannot transition from progenitor states to expressing adult forms and functions, leading to improper adult structural development. Therefore adult structure malformation results, rather than continued larval growth or precocious transition, which depend upon alternate developmental signals functioning.
