Mitosis vs Meiosis
Transcript of Mitosis vs Meiosis
Mitosis produces 2 diploid somatic cells. Meiosis produces gametes or sperm and eggs.
If daughter cells are genetically identical or different
Disadvantages and advantages of each type
Number of divisions
Mitosis only goes through 1 division. Meiosis goes through 2 divisions.
Consistent Chromosome Number
The consistent chromosome number for Meiosis is 46 (2n). The consistent number for Mitosis is 23 (1n).
Number of cells
Their are 2 daughter cells in Mitosis. Their is 4 daughter cells in Meiosis.
Mitosis vs Meiosis
Haploids and Diploids
Diploids are cells that have 2 sets of chromosomes. Haploids only have 1 set of chromosomes. Mitosis creates diploid cells (2n). Meiosis creates haploid cells (1n).
An advantage to Meiosis is that it creates a larger chromosome number than Mitosis. The advantage to Mitosis is that it creates body cells. The disadvantage to Meiosis is that it has to go through 2 divisions. Mitosis doesn't create a large chromosome number.
Mitosis is used to carry out the Cell Cycle. The cell cycle is interphase and the 4 phases. The four phases are Prophase, Metaphase, Anaphase, and Telophase. Prophase is the preparation for mitosis. Metaphase is when the chromosomes go to the middle of the cell. Anaphase is when the chromatids pull away from each other. Telophase is when the 2 new chromosomes are made. Meiosis is used for sexual reproduction in haploid cells called gametes.
Mitosis produces 2 daughter cells that are identical. Meiosis produces daughter cells with one half the number of chromosomes.
Mitosis = n -> n 2n -> 2n
Meiosis = 2n -> n
