What happens during Telophase I in meiotic division?
Options
- AThe homologous chromosomes separate
- BThe nuclear membrane and nucleolus reappear
- CThe chromosomes undergo some dispersion
- DThe replication of DNA occurs
Correct answer
B. The nuclear membrane and nucleolus reappear
Step-by-step solution
The final stage of meiotic prophase I is diakinesis. This is marked by terminalisation of chiasmata. : During this phase the chromosomes are fully condensed and the meiotic spindle is assembled to prepare the homologous chromosomes for separation. By the end of diakinesis, the nucleolus disappears and the nuclear envelope also breaks down. Diakinesis represents transition to metaphase Metaphase I: The bivalent chromosomes align on the equatorial plate The microtubules from the opposite poles of the spindle attach t
