MEIOSIS

PROPHASE 1

• Chromosomes condense and tetrads are formed through synapsis.
• Chromosomes cross over in this stage.

METAPHASE 1

• Tetrads line up, preparing to split
• Align at the metaphase plate

ANAPHASE 1

• Chromosomes move to opposite cell poles

TELOPHASE 1

• Spindle fibers continue to move homologous chromosomes to opposing poles
• Each pole has a haploid number of chromosomes

PROPHASE 2

• The nuclear membrane and nuclei break up while the spindle network appears.
• Chromosomes do not replicate any further in this phase of meiosis.

METAPHASE 2

• The chromosomes line up at the metaphase 2 plate

ANAPHASE 2

• Sister chromatids split.
• Spindle fibers pull apart them to other poles

TELOPHASE 2

• Distinct nuclei form at opposite poles
• Cytokinesis occurs.
• Four daughter cells are produced.
