  • reproduction disadvantages and advantages
    • sexual
      • needs 2 parents
      • produces variation in the offspring
      • if the environement changes variation gives a survival advantage by natural selection
      • negative mutations are not always inherited
      • natural selection can be speeded up using selective breeding to increase food production
    • asexual
      • only one parent needed (quicker)
      • identical offspring (no variation)
      • vulnerable to rapidly changing conditions due to lack of variation
      • negative mutation can affect all offspring
      • food/medicine production can be extremely quick
