Lily Anther Cell Meiosis

Prophase I

Nuclear membrane breaks down, chromatin condenses, spindle forms and attaches to kinetochores.

Metaphase I

Microtubules align homologous chromosome pairs along metaphase plate.

Anaphase I

Kinetochore microtubules shorten, pulling homologous pairs to opposite poles, polar microtubules elongate, lengthening dividing cell.

Telophase I

Nuclear membrane reforms, chromatin decondenses, and cell plate begins to form.

Cytokinesis I

Prophase II

Nuclear membrane breaks down, chromatin condenses, mitotic spindle forms and attaches to kinetochores.

Metaphase II

Microtubules align chromosomes along metaphase plate.

Anaphase II

Kinetochore microtubules shorten, pulling sister chromatids to opposite poles, polar microtubules elongate, lengthening dividing cell.

Telophase II

Nuclear membrane reforms, and chromatin decondenses, and cell plate begins to form.

Cytokinesis II

Completed tetrad.
