- Meiosis is the form of nuclear cell division that results in daughter cells that have one half the chromosome numbers as the original cell.
- In organisms that are diploid, the end result is cells that are haploid. Each daughter cell gets one complete set of chromosomes, i.e., one of each homologous pair of chromosomes.
- In humans, this means the chromosome number is reduced from 46 to 23.
- The only cells that undergo meiosis will become sperm or eggs.
- Mitosis is a continuum process of cell division which occurs in all types of living cells.
- Mitosis involves four basic phases – prophase, metaphase, anaphase and telophase.
- Mitosis is the process where the division of cell occurs by asexual reproduction.
- In mitosis, the nuclear membrane is broken down, spindle fibres (microtubules) attach to the chromatids at the centromere and pull apart the chromatids.
