If you were to treat sperm precursor cells with an agent that completely destroys microtubules (and ensures that they don't reform) at the start of metaphase I, how would this affect meiosis?

A. This would prevent kinetochores from forming on either side of the centrosome during meiosis I.
B. Meiosis I would be interrupted, but meiosis II would proceed normally, since microtubules are not required during this stage.
C. Homologous chromosome pairs would not line up at the cell's center, and the rest of meiosis would not proceed normally.
D. This would only affect the separation of homologous chromosomes during anaphase I, but would not cause any changes to telophase I or subsequent cell division.
