Definition
| Duplicated chromosomes condense. Homologous chromosomes pair up and chiasmata occur as chromatids of homologous exchange parts by crossing over. The nuclear envelope disintegrates and spindle microtubules form. |

|
Definition
| Paired homologous chromosomes line up along the equator of the cell. One homologue of each pair faces each pole of the cell and attaches to the spindle microtubules via the kinectochore. |

Definition
| Homologues separate, are member of each pair going to each pole of the cell. Sister chromatids do not separate. |

Term
|
Definition
| Spindle microtubules disappear. Two clusters of chromosomes have formed, each containing one member of each pair of homologues. The daughter nuclei are therefore haploid. Cytokinesis commonly occurs at this stage. There is little or no interphase between meiosis I and meiosis II. |

Definition
| If the chromosomes have decondensed after telophase I, the recondensed. Spindle microtubules re-form and attach to the sister chromatids. |

Term
|
Definition
| The chromosomes line up along the equator, with sister chromatids of each chromosome attached to the kinectochore microtubules that lead to opposite poles. |
|
|
Term
|
Definition
| The chromatids separate into independent daughter chromosomes, one former chromatid moving toward each pole. |
|
|
Term
|
Definition
| The chromosomes finish moving to opposite poles. Nuclear envelopes re-form, and the chromosomes decondense again. Cytokinesis results in four haploid cells, each containing one member of each pair of homologous chromosomes. |
