|
Mitosis |
Produces identical diploid cells
Occurs after interphase
1 prophase - chromosomes condense 2 metaphase - line up equator 3 anaphase - opposite ends of cell 4 telophase - cell division |
|
|
Meiosis |
1 Produces non-identical haploid cells 2 gametes (sperm and egg) are produced in the gonads (testes and ovaries) 3 Resulting cells only have half the number of chromosomes as the original diploid cells |
|
|
Mitosis and meiosis |
Involve a division of nuclear material followed by a division of cytoplasm( cytokinesis) |
|
|
Meiosis 1 |
Tetrads are formed and crossing over occurs
Produces two haploid cells. Replicated |
|
|
Meiosis 2 |
1 Chromosomes are still composed of two chromatids
2 produces four haploid cells 3 not replicated |
