PART I: Phases of Meiosis Review: Write the name of the phase that corresponds to the description. Include at least one of the descriptions in your answer. Name of Phase Description 1. Homologous chromosomes pair up and form tetrad, Crossing-over occurs 2. Spindle fibers move homologous chromosomes to opposite sides 3. Nuclear membrane reforms, cytoplasm divides, 4 daughter cells formed 4. Chromosomes line up along equator, not in homologous pairs 5. New spindle fibers form 6. Chromatids separate 7. Homologs line up alone equator 8. Cytoplasm divides, 2 daughter cells are formed PART II: Determine the correct order that these cells should go in.
