| 5639325849 | Prophase One | * Chromosomes condense * Paired homologous chromosomes become connected along their lengths by a protein structure called synaptonemal complex * Crossing over occurs * Synapsis ends * Each pair has one or more X-shaped regions called chiasmata * Nuclear envelope breaks down * Microtubules attach to the kinetochores Homologous pairs move towards the metaphase plate |  | 0 |
| 5639325850 | Metaphase One | * Pairs of homologous chromosomes are lined at the metaphase plate * Both chromatids are attached to the kinetochore microtubules |  | 1 |
| 5639325851 | Anaphase One | * Breakdown of proteins allow chromosomes to separate * The homologous chromosomes move towards opposite poles |  | 2 |
| 5639325852 | Telophase and Cytokinesis One | * Completion of the duplication of chromosomes. Cytokinesis is happening simultaneously, forming tow daughter haploid cells * Nuclear envelope forms |  | 3 |
| 5639325853 | Prophase Two | * Spindle apparatus forms * Chromatids move towards the metaphase plate |  | 4 |
| 5639325854 | Metaphase Two | * Chromosomes are positioned at the metaphase plate * The kinetochores of sister chromatids are attached to microtubules |  | 5 |
| 5639325855 | Anaphase Two | * Proteins that held sister chromatids together break down * Chromatids move towards opposite poles |  | 6 |
| 5639325856 | Telophase and Cytokinesis Two | * Nuclei forms * The production of four daughter haploid cells are produced |  | 7 |
| 5639325857 | Character | an observable heritable feature. | 8 | |
| 5639325858 | Trait | any detectable variation in a genetic character. | 9 | |
| 5639325885 | genes | a region of DNA that codes for a protein, and therefore codes for a trait | 10 | |
| 5653023505 | Do you crumple or fold? | Depends on the day. | 11 |
