During which stage of prophase I do the recombined homologous chromosomes of the bivalents tend to separate from each other except at the sites of crossovers, leading to the formation of X-shaped structures called chiasmata?
Options
- AZygotene
- BPachytene
- CDiplotene
- DDiakinesis
Correct answer
C. Diplotene
Step-by-step solution
During the diplotene stage of prophase I of meiosis, the dissolution of the synaptonemal complex occurs.
The recombined homologous chromosomes of the bivalents tend to separate from each other except at the sites of crossovers.
These points of attachment where crossing over has occurred appear as X-shaped structures called chiasmata.
Answer: Diplotene
