Question
Put the events of meiosis in order. Hint: it may be helpful to first group each answer into meiosis I or meiosis II, then order them. Some events in meiosis I and II are similar, so it could get confusing trying to do it all at once.
- 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.
Sister chromatids are pulled to opposite ends of the cell.
- 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.
Crossing over occurs
- 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.
The meiotic spindle forms and the nuclear envelope breaks up. Sister chromatids are held together at the centromere, and homologous chromosomes are already in separate cells at this point.
- 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.
Homologous chromosomes are pulled to opposite ends of the cell. Sister chromatids remain joined.
- 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.
Homologous chromosomes line up with their partner in metaphase.
- 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.
The meiotic spindle attaches to the kinetochores of the homologous chromosomes, one kinetochore per chromosome, with the sister chromatids acting as a unit.
- 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.
Chromosomes condense. The cell contains two homologous copies of each chromosome pair.
- 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.
Nuclear envelopes form and the spindle disappears. Each nucleus holds a single copy of half the number of chromosomes as a diploid cell.
- 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.
The meiotic spindle forms and the nuclear envelope breaks up. Homologous chromosomes are held together at the crossover points (chiasma).
- 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.
Chromosomes line up along the middle of the cell in metaphase.
- 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.
Nuclear envelopes form and the spindle disappears. Each nucleus holds half the number of chromosomes as a diploid cell, but those chromosomes consist of two sister chromatids at this point.
