| Question | Answer |
|---|---|
| Interphase 1 (2n diploid) ...3 | - nucleus - chromatin - centrisome |
| Prophase 1 ...3 | - chiasmata - nuclear envelope breaks down - chromosomes condense |
| Metaphase 1 ...4 | - independent assortment - centromere - homologous chromosomes line up at equator - miotic spindle attaches to centromere |
| Anaphase 1 ...4 | - reduction division - homologous chromosomes separate - reduction division - fibres contract |
| Telophase 1 (n haploid) ...3 | - cytoplasm starts to separate - nucleus membrane forms - contractile ring pinches |
| Cytokenisis 1 ...1 | - seperate nucleus forms |
| Prophase2 ...1 | - nuclear membrane breaks down |
| Metaphase 2 ...1 | - chromosomes line up at the middle |
| Anaphase 2 ...1 | - sister chromatids seperate |
| Telophase 2 ...1 | - contractile ring pinches and cytoplasm starts to separate |
| Cytokenisis 2 ...2 | - 4 genetically unique haploid daughter cells (gametes) - nucleus |
