Mitosis vs. Meiosis
Stages | Meiosis | Mitosis |
Interphase | - begins with a diploid cell | - begins with a diploid cell |
Prophase | - four chromosomes combine to form two tetrads - the chromosomes in the tetrad cross over each other, allowing them to exchange genetic material | - four chromatids combine to form two chromosomes linked by a centromere |
Metaphase | - the two tetrads line up in the center | - the two chromosomes line up in the center |
Anaphase | - the two tetrads split up into four chromosomes which go to both poles | - the two chromosomes split up into four chromatids which move to both of the poles |
Telophase | - the two sets of chromosomes become enclosed by the nuclear envelope | - the two sets of chromatids are enclosed by the nuclear envelope |
Cytokenesis | - two cells are formed with two sets of chromosomes in each one | - two cells are created with two chromatids in each one. - mitosis is now complete. |
Prophase II | - DNA replication is skipped and the two cell's nuclear envelope are dissolved and the spindle reformed - the four chromatids in each cell are connected together to form two chromosomes | |
Metaphase II | - the two chromosomes line up in the center | |
Anaphase II | - the two chromosomes are split up into their daughter chromatids and moved towards opposites poles | |
Telophase II | - the nuclear envelope is reformed around the two poles on each cell. | |
Cytokenesis | - the cells are split up again and four haploid cells remain as a result - meiosis is now complete |
