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.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
