Study Notes
Meiosis Stages
- Synapsis occurs during the prophase I stage of meiosis.
DNA Replication
- DNA replication in meiosis results in the doubling of chromosomes, producing identical sister chromatids.
Metaphase I
- In metaphase I, homologous chromosomes align at the cell's equator.
Crossing Over
- Crossing over occurs in prophase I of meiosis, allowing for genetic recombination.
End of Meiosis II
- At the end of meiosis II, the resulting cells are haploid (1n).
