Prophase 2: nuclear envelope breaks down, spindle fibers and centrioles appear
Metaphase 2: apindle fibers attach to centromeres, and chromosomes line up singularly across middle of cell
Anaphase 2: spindle fibers shorten and seperate the chromosomes, sister chromatids are pulled apart and move to opposite ends of the cell
Telophase 2 and Cytokinesis: Spindle fibers disappear and the nuclear membrane reforms, the cell me brane pinches inward and two cells are formed, 4 haplod cells are produced, 2 from each division

Haploid: 1 set of chromosomes
Diploid: 2 sets of chromosomes

when homologus chromomes come very close to each other and exchange potions of their chromatids

Interphase 1: cells increase in size, produce RNA, synthesize proteins, and replicate DNA
Prophase 1: nuclear envelope breaks down, spindle fibers and centrioles appear, chromosomes form a tetrad, and crossing-over occurs
Metaphase 1: Spindle fibers attach to centromeres, homologous chromosomes line up in pairs across middle of cell
Anaphase 1: Spindle fibers shorten and pull chromosomes apart, chromosome from each pair moves to opposite end of cell
Telophase 1 and Cytokinesis: Spindle fibers disappear and nuclear enevelope reforms, cell membrand pinches inward and 2 haploid cells are formed
