1. Prophase I: crossing-over occurs between tetrads
2. Metaphase I: Paired homologous chromosomes line up across the center of the cell
3. Anaphase I: Spindle fibers pull each homologous chromosome pair toward an opposite end
of the cell
4. Telophase: A nuclear membrane forms around each cluster of chromosomes and cytokinesis
follows, forming two new cells
5. Prophase II: Chromosomes consist of two chromatids, but they do not pair to form tetrads
6. Telophase II: A nuclear membrane forms around each cluster of chromosomes and
cytokinesis follows, forming four new cells.
7. Mitosis: Form of reproduction: Asexual
8. Meiosis: Form of reproduction: first stage in sexual
9. Mitosis: Number of daughter cells: 2
10. Meiosis : Number of daughter cells: 4

11. Mitosis: change in chromsome number: No change; stays diploid
12. Meiosis: change in chromsome number: cut in half to haploid
13. Mitosis: Number of cell divisions: 1
14. Meiosis: Number of cell divisions: 2
15. Mitosis: Difference in alleles between parent cell and daughter cells: none
16. Meiosis: Difference in alleles between parent cell and daughter cells: Each of the four
daughter cells is genetically different from the parent
