← Nature & AnimalsWhich developmental abnormality occurs when insects have mutations affecting hormone targeting imaginal discs?
A)Organs fail to fully develop at metamorphosis✓
B)Larval molting occurs prematurely under stress
C)Ecdysis failure due to cuticle malformation
D)Disrupted patterns during somatic embryogenesis
💡 Explanation
When hormone signal transduction pathways have mutations preventing access to the imaginal discs, the cell differentiation programs cannot execute properly during pupation, resulting therefore, organs missing crucial late-stage processes compared to earlier ones; as such malformations of the adult occur; B, C and D do not relate the effect hormone regulation and development.
