Presentation transcript:

Mitosis and Meiosis

Mitosis The process where a single cell divides resulting in two identical cells, each containing the same number of chromosomes and genetic content as that of the original cell Mitosis

Phases of Mitosis There are 4 main phases of Mitosis: Prophase Metaphase Anaphase Telophase

Meiosis A process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus, which results in the production of sex cells Phases of Meiosis

Phases of Meiosis

Phases of Meiosis There are 8 main phases of Meiosis Prophase II Metaphase II Metaphase I Anaphase II Anaphase I Telophase II Telophase I

What type of cells are made? Mitosis Meiosis The process of mitosis is the reproduction of somatic cells, or body cells. Ex: hair cells, skin cells The process of meiosis is the reproduction of sex cells Ex: Egg and Sperm

Genetic Variation Mitosis Meiosis Daughter cells are identical to their parent. The DNA and genetics are copied and reproduced to form new cells. The daughter cells have the exact 46 chromosomes as the parent cell. The daughter cells are similar to the parents cells but not identical. Daughter cells only have 23 chromosomes because they must meet up with another sex cell to reproduce an offspring.
