reproduction

• • Gametes: sex cell (meiosis)
• • Auto somal: body cell (mitosis)
• • Haploid: 1 set of chromosomes 
• • Diploid: 2 sets of chromosomes
• • Gametes have 46 chromosomes 
  • Auto somal cells have 23 chromosomes 
• • Meiosis gives rise to 4 cells, mitosis gives rise to 2 cells
• Interphase: 

  • G1: Growing + replicating organelles
  • S: Duplicating the DNA
  • G2: Prepping to duplicate cell and centrosomes duplicate 
• Mitotic Phase:

  • Prophase: 
  • Nucleus dissolves 
  • Chromatins ⇾ Chromosomes 
  • Centrosomes migrate 
• Metaphase:

  • Nucleus disappears 
  • Chromosomes line up in the middle
  • Spindles 
• Anaphase: 

  • Cleavage furrow 
  • Chromosomes move away
• Telophase: 

  • Cleavage furrow deepens 
  • Nucleus reforms
• Cytokinesis:

  • Both cells separate
