Homologous chromosomes in zygotene pair due to attraction and synaptonemal complex formation. Which of the following is true for diplotene phase?

Homologous chromosomes in zygotene pair due to attraction and synaptonemal complex formation. Which of the following is true for diplotene phase? Correct Answer The synaptonemal complex breaks down

In the diplotene stage the chromosomes repel each other and synaptonemal complex breaks down. Repulsion can’t be due to opposite charge but like charge, also they don’t separate completely but are joined at the crossing over sites which gradually terminalize.
