- Prophase 1: chromatin condenses, chromosomes shorten thicken.
- homologous pairs form bivalents
- crossing over, non-sister chromatids wrap around at the chaismata
- nuclear envelope breaks down, spindle forms
- Meiosis
- Metaphase 1: bivalents to equator.
- spindle by centromere
- bivalents randomly assorted each memeber of homologous pair faces opposite poles
- anophase 1: homolougous chromosomes pulled to opposite poles
- chiasmata seperate, crossed over sections remain in new place
- telophase 1: 2 new nuclear envelopes reform
- cell divieds by cytokenisis
- brief interphase- does not happen with plants
- prophase 2: nuclear envelopes breaks down, nucleolous disapears
- spindles form
- chromosomes condense
- spindles form
- anaphase 2: centromeres divide, chromatids pulled to opposite poles
- telophase 2:nuclear envelope reforms
- 4 haploid cells produced (daughter)
- Metaphase 1: bivalents to equator.
- metaphase 2: centromeres attach to spindle at equator
- chromatids and chromosomes randomly assorted
