Prophase I
Chromosomes condense, nuclear membrane dissolves, homologous chromosomes form bivalents, crossing over occurs
Metaphase I
Spindle fibres from opposing centrosomes connect to bivalents (at centromeres) and align them along the middle of the cell
Anaphase I
Spindle fibres contract and split the bivalent, homologous chromosomes move to opposite poles of the cell
Telophase I
Chromosomes decondense, nuclear membrames may reform, cell divides (cytokinesis) to form haploid daughter cells
Prophase II
chromosomes condense, nuclear membrane dissolves, centrosomes move to opposite poles
Metaphase II
Spindle fibres from opposing controsomes attach to chromosomes and align them along the cell equator
Anaphase II
Spindle fibres contract and seperate the sister chromatids move to opposite poles
Telophase II
Chromosomes decondense, nuclear membrane reforms, cell divide to form four haploid daughter cells
