summary - meosis 1 and 2

• • Mitosis occurs both in diploid and haploid cells
  • Meiosis only occurs in diploid cells
• • DNA Replication
  • Mitosis occurs during interphase before mitosis begins
  • Meiosis occurs during interphase before mitosis 1 begins
• • NO. OF DIVISION
  • Mitosis one 
  • Meiosis two; meiosis 1 and meiosis 2
• • Synapsis of homologous chromosomes
  • Mitosis does not occur
  • Meiosis occurs during prophase 1 w/ crossing over
• • NO. OF DAUGHTER CELLS 
  • Mitosis two, identical to the parent cell
  • Meiosis four, genetically different from the parent cell and from each other
• • Role in the animal or plant body
  • Mitosis growth, repair
  • Meiosis produces gametes (animal) or spores (sporophyte plant); reduces number of chromosomes sets by half
• Haploid cells - chromosomes ay may 23 from male, 23 from female, 23 from daughter cells

  • Contain half of the chromosomes/ contains only one set of chromosomes (n)
  • Product ng meiosis is 4 haploid cells
• • Diploid cells chromosomes are buo pa (46 from male, female, and daughter cells)
  • Contains two set of chromosomes (2n)
  • Product ng mitosis is 2 diploid cells
• • Meiosis purpose is to produce offspring
  • Meiosis results to 4 haploid cells
  • There is no synapsis in mitosis because there is no crossing over
• • Cytokinesis division of the cell cytoplasm (where you can find all cell organelles)
  • It happens after telophase
