What is the function of diakinesis stage?
Options
- ATo prepare the homologous chromosomes for separation
- BTo pair the chromosomes together
- CTo form the tetrads
- DTo form the synaptonemal complex
Correct answer
A. To prepare the homologous chromosomes for separation
Step-by-step solution
These X-shaped structures, are called chiasmata. In oocytes of some vertebrates, diplotene can last for months or years. The final stage of meiotic prophase I is diakinesis. This is marked by terminalisation of chiasmata. 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 a
