Stages of meiosis

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
