Metaphase 1 centrioles move to opposite poles of the cell a spindle has formed bivalents line up at equator
Telophase 1 nuclear envelope reforms cytokinesis of the cytoplasm occurs but this is not always complete reduction of the chromosome number- diploid to haploid
Prophase 2 nuclear envelope breaksdown nucleolus disapears chromosomes condense centrioles move to opposite poles of the cell
Metaphase 2 pairs of chromtids line up at the equator spindle gibres attach to the chromosomes at centromere chromatids of each chromosome are randomly assorted
Anaphase 2 spindle fibres contract and pull the chromatids to opposite poles
Telophase 2 nuclear envelope reforms around haploid daughter nuclei spindle fibres breakdown centrioles reform
