2.2. Conservation Levels

k-mers are distributed into any of these conservation levels based on their index incidence value:

  • completely conserved (black) (index incidence = 100%),

  • highly conserved (blue) (90% ≤ index incidence < 100%),

  • mixed variable (green) (20% < index incidence ≤ 90%),

  • highly diverse (purple) (10% < index incidence ≤ 20%) and

  • extremely diverse (pink) (index incidence ≤ 10%).
