Answer:
Chromosome condenses 
Pairing up to form tetrad
Crossing over 
Lining up on metaphase plate
Homologous chromosome separate 
Explanation:
Condensation of chromosomes occurs in prophase I phase. Pairing up to form tetrad occur during prophase I. Crossing over occurs during prophase I of meiosis cell division. Chromosomes line up along the metaphase plate in the stage of Metaphase. Centromeres break down and homologous chromosomes separate in anaphase I phase of meiosis.
