Chapter 7- Meiosis
| Term | Definition |
|---|---|
| meiosis | a form of cell division that halves the number of chromosomes when forming gametes |
| spermatogenesis | process by which sperm are produced |
| oogenesis | process by which eggs (ova) are produced |
| prophase I | the chromosomes condense, and the nuclear membrane breaks down, crossing over occurs |
| metaphase I | the pairs of homologous chromosomes are moved to the equator of the cell |
| anaphase I | the homologous chromosomes separate |
| telophase I | nuclear membrane forms around the chromosomes, 2 cells move into cytokinesis |
| prophase II | after one division, new spindle fibers form in the two cells |
| metaphase II | individual chromosomes line up along the equator, attached at their centromeres to the spindles |
| anaphase II | the centromeres divide, and the chromatids move to opposite poles of the cell |
| telophase II | nuclear membrane forms around the chromosomes, 4 cells move into cytokinesis |
