| How many parts are there to meiosis? | There are 2 parts |
| What happens during the first part of Meiosis? | Separation of homologous chromosomes |
| What are the 2 parts of Meiosis called? | Meiosis 1 and Meiosis 2 |
| What happens in the 2nd part of Meiosis? | The separating of chromatids |
| What is the result of Meiosis? | the production of four haploid cells from a diploid cell |
| What type of reproduction is Meiosis? | Sexual Reproduction |
| Copies of chromosomes are held together by ? | Centromeres |
| Crossing over points are called? | Chiasmata |
| Dna Replication takes place when? | Interphase |
| In prophase 2, each cell is ? | Haploid |
| When does crossing over occur? | Prophase 1 |
| During which phase do chromosomes line up along the equator? | Metaphase 1 & 2 |
| During which hase does the nuclear membrane form around the chromosome? | Telophase |
| When do chromatids separate? | Anaphase 2 |

| Your result of meiosis, are the cells haploid or diploid? | Haploid |
| Meiosis is different then Mitosis, How? | At the end of Meiosis your left with 4 cells instead of 2 identical ones. |
| What happens in interphase? | Cell growth and DNA replication |
| In Meiosis 2 how many cells do you have? | You now have 2 |
