- 1Meiosis I prophase IHomo Reco.
Formation of bivalents via synapses, with crossing over at chiasma. - 25 phases of prophase I1. Leptotene
2. Zygotene
3. Pachytene
4. Diplotene
5. Diakinesis - 3LeptoteneDuplicated chromo start to condense
- 4ZygoteneSynapsis begins
Synaptonemal complex forming - 5PachyteneSynapsis complete
Crossing over occurs - 6DiploteneSynaptonemal complex disappearing
Chiasma visible - 7DiakinesisBivalent ready for metaphase
- 8Scaffolds of synaptonemal complexLateral elements
Central element - 9Metaphase IBivalents at equator
One KC per chromo - 10Telophase IChromo decondense
N. membrane may reform, usually doesn't - 11Meiosis IIResembles mitosis but w/ 1/2 chromosomes
- 12CytokinesisActin + myosin filaments of the contractile ring associated w/ PCM
MT walked in opposite directions to one another, push against each other, contribute to constriction.
Contractile ring causes cleavage furrow - 13Plant cell cytokinesisPhragmoplast in centre
MT trapped
Forms pore through which plasmodesmata pass - 14Cytokinesis in drosophilaDrosophila embryo mitosis occurs without cell division
PCM full of nuclei
