38. Chiasmata are essential for proper segregation on the meiotic spindle because they provide the physical tension, or glue, that the microtubules pull against. If the centromere of each replicated pair attaches to a different spindle pole, then as the microtubules pull, the chromosomes will align in the middle of the spindle.
