Question

Why do chiasmata hold homologs together in meiosis I?

Answer 1

Chiasmata hold homologous together in meiosis I because:

1. During the diplomatic phase of meiosis I, homologous chromosomes begin to separate but are retained by Chiasmata.
2. Chiasmata is required for the connection of homologous chromosomes with opposite spindle poles during meiosis I and for the separation of subsequent opposite poles.
3. The chromosome in anaphase I remove cohesive from the arms.
4. Which in turn separates the homologs, which allows their separation at the opposite poles of the first mycotic spindle.
5. After this, the spindle is disintegrated and the cell moves directly to another mycotic division.
