  • Investigating variation
    • Types
      • Interspecific
        • Variation between species
    • Sampling
      • Involves taking measurements of individuals selected from the population being tested
        • In theory if these individuals are representative of the population as a whole then the measurements can be relied upon
          • Could be affected by sampling bias or by chance e.g. selecting the tallest people to measure the height of.
            • sampling bias could be reduced by random sampling
            • Chance could be reduced by having a large sample size and by doing statistical tests on the data collected
    • Caused by
      • Mutations
      • Fusion of gametes
      • Meiosis
