Prophase 1: The chromosomes condense and homologous chromosomes pair up and cross over creating variation.
Metaphase 1: The homologous chromosome pairs line up at the equator and attach to spindle fibres.
Anaphase 1: The spindle fibres contract separating the homologues pair, which moves to opposite poles.
Telophase 1: The nuclear membrane forms around the each pole of the cell forming two new cells each containing 23 chromosomes (haploid), which contain 23 pairs of chromatids.
Metaphase 2: This occurs in both new cells, the chromosomes independently line up on the equator of the cell and are again attached to the spindle fibres.
Anaphase 2: The spindle fibres shorten which causes sister chromatids, of the same chromosome, the separate from each other at the centromere. The chromatids then move to opposite poles of the cell.
Telophase 2: The nuclear membrane forms around each pole the two cells creating 4 haploid cells.
Cytokinesis 2: The cells completely separate.
