Meiosis Cells that undergo meiosis, also go through the G1, S, & G2 phases of Interphase then enter the Cell Reproduction step Process of cell division that reduces the number of chromosomes contained in the cell by half This results in FOUR HAPLOID cells instead of two diploid cells as in Mitosis

Prophase I: - Nuclear membrane disappears Crossing over occurs where chromosomes exchange genetic information Ensures genetic variability This is why you and your siblings may have different colored hair or eyes, even though you have the same parents

Metaphase I: Anaphase I: Telophase I Cytokinesis I: Chromosomes line up Anaphase I: The chromosomes split & move to opposite ends of the cell Telophase I Chromosomes reach opposite ends of the cell Cytokinesis I: & the cell splits into TWO DIPLOID cells

Prophase II: Nuclear membrane disappears Metaphase II: Chromosomes line up Anaphase II: Chromatids separate and begin moving away from each other

Telophase II Nuclear membrane surrounds each new chromosome set Cytokinesis II: & the cell splits into TWO MORE CELLS
