| A | B |
|---|
| Meiosis | doubles the genetic material of normal haploid cells |
| Prophase1 | Tetrads formed (synapsis) , crossing over takes place(2 nonsister chromatids share genetic material) |
| Metaphase 1 | tetrades align on center plate, DNA replicates |
| Anaphase 2 | sister chromatids seperate from homologous chromosomes |
| Telophase 1 | cells considered haploid because the have a single set of chromosomes. |
| prophase 2 | just like mitosis except starting with haploid number |
| Synapsis | during prophase 1, the duplicated chromosomes pair with their homolougus. |
| crossing over | occurs during prophase of meiosis 1 |
| chiasmata | location of crossing over |
| Interphase 1 | chrom. replicate and sister chromatids attach at centromere |
| Anaphase 1 | homo. pairs seperate and move toward opp. poles. Centromeres do not seperate. |
| Metaphase 2 | haploid sets of chromo. line up at meta. plate |
| Homologous chromosomes | have genes for the same traits at the same loci |
