Question #46227
The Question
A researcher treats the axillary buds ('eyes') of a potato tuber with a chemical that specifically inhibits the Anaphase Promoting Complex (APC). Which of the following accurately describes the immediate cytological consequence and its effect on the plant's natural propagation strategy?
Options
- A.
Cells will arrest at the G2/M transition, completely halting bud sprouting and preventing vegetative propagation.
- B.
Sister chromatids will fail to separate, resulting in polyploid progeny and the loss of strict clonal fidelity.
- C.
Homologous chromosomes will fail to segregate, leading to aneuploid shoots that disrupt rapid colonization.
- D.
The cells will undergo rapid amitosis to compensate for the spindle failure, maintaining the diploid clonal lineage.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Integrating Cell Cycle regulation (APC function) with Plant Reproduction (Vegetative propagation).
The primary trap is Option C, which tests the common misconception of confusing mitotic sister chromatid separation with meiotic homologous chromosome segregation.
Option A tests the exact location of the cell cycle arrest (Metaphase vs G2).
