Sketch the Phases of Meiosis
1. What is the diploid number for the cell? ______ haploid number? _____
2. How many daughter cells are produced at the end of meiosis 1? _____ meiosis 2? ______
3. During what phase do homologous chromosomes separate? _______________
During what phase do individual chromatids separate? __________
4. During which phase do homologous pairs line up in the center of the cell? _______________
5. During which phase does crossing-over occur between homologous pairs? ______________

Answer 1

1. Diploid number = 6 (2n = 6). Haploid number = 3 (n = 3).

2. Daughter cells after meiosis I = 2. After meiosis II = 4.

3. Homologous chromosomes separate during Anaphase I. Individual sister chromatids separate during Anaphase II.

4. Homologous pairs line up at the cell center during Metaphase I.

5. Crossing-over occurs during Prophase I (during the pairing/tetrad formation stages).
