• meiosis occurs in sexual reproduction, production of gametes
• human reproductive organs testes and ovaries
• plant reproductive organs anther and ovary
• meiosis makes 4 non identical, randomly genetically unique daughter cells
• diploid cells by mitosis produces two cells which contain identical sets of chromosomes
• haploid number of chromosomes is 23
• diploid number of chromosomes is 46
• mitosis occurs in growth (more cells, not larger) repair (more cells to replace lost in injury) asexual reproduction (usually in single celled organisms) cloning (genetically identical)
