During Metaphase I, the bivalents align at the equatorial plate. How do the spindle fibers attach to the chromosomes?
Show answer and explanation
Correct answer: To the kinetochore of homologous chromosomes
In Metaphase I, microtubules from opposite poles of the spindle attach to the kinetochores of the homologous pairs. This allows the whole chromosome (with both chromatids) to be pulled toward a pole.
