← Nature & AnimalsFollowing irreversible removal of the corpus allatum in Drosophila larvae, which outcome occurs?
A)Precocious metamorphosis into small adults✓
B)Prolonged larval stage with gigantism
C)Arrested development in permanent larval form
D)Normal pupation proceeds to sterile adults
💡 Explanation
When the corpus allatum is removed, juvenile hormone production ceases causing a shift to metamorphosis spurred by ecdysone, resulting in small adults due to fewer larval molts feeding periods. Therefore precocious metamorphosis of small adults results,rather than size modification, which relies on growth-inhibiting mechanisms associated with imaginal disc hormones.
