The separation of homologous chromosome starts in the:
Correct answer: B. Diplotene
- A. Zygotene
- B. Diplotene
- C. Pachytene
- D. Diakinesis
Explanation
In the Zygotene, homologous chromosomes start pairing which completes in the pachytene, where crossing over occurs. In diplotene, these paired chromosomes repel each other and begin to separate. The separation of homologous chromosomes is still not complete because chromosomes remain united by chiasmata. Separation of homologous completes in anaphase 1.
