1. Mitosis:
* Parent cell: Has a full set of chromosomes (diploid).
* Daughter cells: Identical to the parent cell, also with a full set of chromosomes (diploid).
* DNA difference: No difference. Daughter cells are genetically identical clones of the parent cell.
2. Meiosis:
* Parent cell: Has a full set of chromosomes (diploid).
* Daughter cells: Have half the number of chromosomes as the parent cell (haploid). They are gametes (sperm or egg cells).
* DNA difference: Significant difference. Daughter cells have a unique combination of chromosomes due to:
* Crossing over: Exchange of genetic material between homologous chromosomes during prophase I.
* Independent assortment: Random alignment of homologous chromosomes during metaphase I.
In summary:
* Mitosis results in daughter cells with identical DNA to the parent cell.
* Meiosis results in daughter cells with unique DNA compared to the parent cell and each other.
Important note: While there are significant differences in DNA content between parent and daughter cells in meiosis, these differences are still based on the original DNA from the parent cell. They are not entirely new genetic information.
