  • Gene mutations
    • Small scale mutations
      • Substitution
        • One or more bases are swapped for another (ATG becomes ATT)
      • Deletion
        • One or more bases are removed (ATG becomes ATC)
      • Insertions
        • One or more bases are added (ATGCCT becomes ATGACCT)
    • Large scale Mutations
      • Translocation
        • A sequence of bases is moved from one location the genome another. This could be movement within the same chromosome or movement to a different chromosome.
      • Inversions
        • A sequence of bases is reversed (ATGCCT becomes ACCGT)
